Bug in JVM
I was trying to call Unsafe.defineClass() method of the class Unsafe but it always returns null
the line code is
defineClass(name, arr, 0, arr.length) ;
I opened the jvm.dll in hexeditor and found that there is no entry for this method in jvm.dll also.
is this an error or I should use a different method.
Please help me ...
thanks
Sorry i missed it is happening with jdk1.6 only. while working fine with jdk 1.5 and earlier versions.
I have tried it with jdk 1.6 update 1 also but it fails.
thanks

Hello all.
Whenever I try to make JNI calls to Ms Word in multiclient environment on server, the JVM closes with the following message.
Another exception has been detected while we were handling last error.
Dumping information about last error:
ERROR REPORT FILE = (N/A)
PC = 0x19BFC46D
SIGNAL = -1073741819
FUNCTION NAME = (N/A)
OFFSET = 0xFFFFFFFF
I am using JRE1.4.0 .
The heap size of JVM I have set is 256 MB.
Is this a bug in JVM?
Please guide me in this problem if possible because it is urgent for me.
Thanks in advance.Hallo,
if I understand your problem correctly, you are trying to call MS Word on your server from Java code in your server. This is not to be recommended!
I have seen references to this problem elsewhere in the Sun forums but cannot at the moment find them. There is also something in MSDN. As far as I remember, the story goes like this:
1. Word is a program for client PCs.
2. Word expects to have a GUI available for it to display messages and so on.
3. Although you can control Word over OLE, 1 and 2 above still apply.
4. If you still want to use Word in your server, then on your own head be it. -
Hi All,
We are using hotspot JVM 1.4.2_05 for one of our J2EE applications. The J2EE server is WebLogic 8.1 Sp2.
We are facing a problem with sudden JVM crash after the perm gen getting utilized to till 99%.
We tried with maxPermSize as 64 MB as well as 128MB. But in both the cases the JVM uses total perm gen something around 45-46 MB.
We are unable to understand even in case of 128MB of maxPermSize why JVM is not able to increase the total perm gen and instead went for a crash. Is it a bug in this specific JVM version ?
Any pointer/idea would be really helpful.
Regards,
SouravHi Cfuishien,
Thanks again for your input.
We actually ran it again without -Xbatch and with -XX:+PrintCompilation. The system crashed. I'm adding here the top part of the pstack output and the last part of the massege appeared in log file at the time of crash.
Please let me know if you need any further input.
pstack output -

A question about Oracle installer and a possible bug in JVM
Hello,
I appreciate if you could kindly guide me to solve the following problem.
I'm trying to install Oracle11g Enterprise on a Linux system (Redhat Enterprise 5.3).
There is no X system, and therefore I chose to install by using a response file
in silent mode. I set the parameters value as indicated in Oracle installation
guide. Yet, when I launch the installer, it seems that there is a problem with
java:
[oracle@ccsaplinux0002 database]$ ./runInstaller -responseFile /usr/local/oracle/database/responseFileV01.rsp -silent
Starting Oracle Universal Installer...
Checking Temp space: must be greater than 80 MB. Actual 34517 MB Passed
Checking swap space: must be greater than 150 MB. Actual 8189 MB Passed

[oracle@ccsaplinux0002 database]$I looked in the oracle package that I downloaded, there was no jdk or jre direcotry.
As a result I downloaded the JDK 1.6.0_15 available on Sun microsystem web site and then
I set manually in oracle user ~/.bash_profile the value for $JAVA_HOME.
Why I get this error?
Thanks in advance,
Dariush

Hi people,
Since we switched from JRE 1.5.0_08 to 1.5.0_11_64, we are encountering application freezes due to infinite full GC loops.
Sun mentionned this runtime problem as bug 6545719 (*http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6545719*) since jre 1.5.0_11 fixed in version 1.5.0_15.
I asbolutely need to reproduce the bug before we switch to jre 1.5.0_15. The problem is that i can't find the PermLeak.java class mentionned in the URL above.
Can anybody tell me how/where can i get this class?
Thanx in advanceThe test case was submitted by a third party, so we (Sun) need approval to release it. It's easier to describe how to write your own test. Use an infinite loop that appends to a string variable s and then calls s.intern() on each iteration. You want s to fill the permanent generation (default 64MB), so best to grow it quickly. You also need to use s somewhere in the loop, by printing out part of it, or printing its length. Otherwise if the method is compiled it might get optimized away. Good luck.

Investigation on JVM crash without core dump (by JIT compiler)
Hi, All
I posted "JVM crash without core dump due to CompilerThread1" couple months ago.
http://forum.java.sun.com/thread.jspa?threadID=5253434
I would like show what we found, and ask couple questions
1) The reason of JVM crash is "CompilerThread0/1 wanted to allocate more native memory and eventually exceeded the limit of 32-bit Linux (on Redhat, the limit of VIRT is 3G)
2) After we lower the heap size (to reduce process size) and added process size monitor (track process size every minute) and JIT compilation log (-XX:+PrintCompilation),
We found sometimes JVM process jumped more than 800M when compiling one method. with the following log
Total time for which application threads were stopped: 0.1997400 seconds
5828 xxx.xxx.SomeClass::someMethod (1507 bytes)
5828 COMPILE SKIPPED: out of nodes during split (not retryable)
549002.449: [GC [PSYoungGen: 517897K->28390K(551296K)] 942855K->453348K(1229952K), 0.0726350 secs]
if we saw "COMPILE SKIPPED: out of nodes during split (not retryable)", the process size of JVM (VIRT/RES) always jumped 800M~1000M, and sometimes the memory get reverted in 30mins to couple hours, and sometimes it lasted forever. (so before we have larger footprint, this jump will kill JVM, right now, if the jump lasts forever, any more allocation on top of it also can kill jvm (much rare))
3) This is definitely a bug of JVM, because
it only happened on server mode, not client mode
it is random, that method can be compiled success on other JVM or next restart (we have 20 JVMs)
the method is not that complicate, like 100 lines, (bigger method gets compiled success)
this only happen on PROD environment, we can't reproduce it locally or QA (the method is always compiled success)
It mostly like under some condition (maybe node space is not enough), to compile that method will trigger JVM trying to allocate much more native memory.
4) We are going to disable this method by ".hotspot_compiler" to fix it, right now we are using lower footprint, JVM dies rarely.
+To understand more about this, I have some questions about JIT compiling+
I saw same method are compiled more than once from JIT log, like the method caused our problem, it only happens on 2nd time compilation.
Is it that JIT compiler will recompile the method with deeper optimization level some time, and more optimization it uses, the more memory it requires?
(like gcc has -O2 -O3)
Thanks!
NeoToday, one JVM crashed again, with

It leaks gradually when executing it for a long time.
It makes the generation of the memory leak disregarding timeout error of the
connection a problem.
Is this a bug of JVM?
Or, is it a problem of coding?
Environment:
JVM Sun JVM 1.5.0_6
OS RedHat Enterprise Linux ES 3 update6 (kernel 2.4.21-37ELsmp)I was searching on Google for "java Calendar memory leak", and I ran across this post. Now, I haven't examined your code but I do see you make a lot of calls to getInstance() in java.util.Calendar, and I am having the same kind of issue as you are describing. So I took the Calendar class out (no more getInstances) and now the memory is still increasing but at a MUCH slower rate, and the CPU time is down drastically. I do not know if this is the cause because I haven't seen it documented, but it would be great if someone could confirm this for me. Maybe try removing the Calendar getInstances and find another way to do it, like using System.getCurrentMillis and working from there to get the hours (that's what I did.)
Hope this helps,

Solaris 10, amd64, JVM crash at short time after startup
Hi All,
I have an application which allocate 10G of memory for his Heap, run on 4 dual core amd64 CPUs, 16G RAM machine and crash in 98% of the cases at short time after startup. This is a customer machine.
I have a similar machine for tests with only 2 dual core amd64 CPU and 12G RAM and I don't experience any crashes running application with similar configuration, similar version of JDK and similar input data.
I have tried with different GC algorithms, but we obtain crashes sonner or later. I rare cases when application manage to start seems that CMS offer the greatest performance.
There is a bug in JVM? Knows anybody an workaround for this?

}Edited by: blue67 on Dec 10, 2007 12:57 AMI've experienced the same crash problem for my application in a Sun Fire x4600 M2..
My application which allocates 50G of memory for his Heap, runs on 8 quad core amd64 CPUs, 64G RAM machine and crash in 98% of the cases at short time after startup.
If I run my application on a different machine, for example a Sun Fire 280R with 2 CPUs UltraSPARC-III+ 1.2Ghz 8MB, there are no crashes.
I think the problem is related to the AMD 64 bits CPU architecture.
I filed a bug to the Sun Bug DB with ID 1415527, but it hasn't been published yet.
I cannot understand why, since it seems to be a problem common also to other users.
Here's part of my last hs_err_pidXXX.log file:

Thanks -
I run a complex server app on JDK1.3.0 IBM AIX4.3.3. JVM crashes (process terminates) occasionally after a random period of time e.g. several days. Native code caused SIGILL (illegal instruction) and process was terminated by OS as shown in nuhop.out. (I run it with nohup.)
BTW, JVM has enough free memory during its running.
Would anyone tell me possible reasons for JVM crash? Can I say that if JVM crashes, no matter what app it runs, it is a bug of JVM? Need help on locating problem.
Thanks.Can I say that if JVM crashes, no matter what app it
runs, it is a bug of JVM?No, you cannot. I have seen numerous instances where a JVM brought down the whole process because it caught a signal in some native code outside of the JVM - either in the OS libraries themselves or somewhere else in the programmer's code. In this case since you are getting a SIGILL, the probability of a bug in the OS or the JVM itself seems a bit higher to me than if you just saw, say, SIGSEGV.
Would anyone tell me possible reasons for JVM crash?Well you probably want to make sure that it is not due to any native code of yours first (or from a 3rd party, like a JDBC driver vendor, for example), if you have any... I find myself answering these kinds of posts often, partially because I have seen this kind of thing numerous times and think that I might be able to help, though it seems some of these questions are asked a little too often...
Anyway, see this:

Setup for Discoverer to have multiple sessions opening in different browser
What is the setup for Discoverer or Windows 6 browser to have multiple discoverer sessions opening in different browser windows at the same time in Discoverer 10g Plus?
We have implemented Discoverer 10g Plus just to be used as an extract tool. We have some workbooks retrieving 200,000 or more rows from an Oracle database. It is taking 30 to 45 minutes to download. Some users are able to open multiple sessions in different browsers to download more then one worksheet at the time, but we have other users who get an error message that they can only open one session at the time. What is the setup to allow users to open more than one Discoverer session?Additional research in Metalink found the following:
Hdr: 7261918 10.2 USER_JAV 10.1.2.54.25 PRODID-964 PORTID-46
Abstract: ALLOW ABILITY TO LAUNCH TWO DISCOPLUS SESSIONS FROM SAME BROWSER CONNECTION PAGE
*** 07/17/08 07:31 am REQUEST TEXT ***
Please refer to bug 6656139. Need to get Discoverer Plus certified to
support launching two plus sessions from same browser connections page when
using SUN JRE 1.5/1.6 or higher.
As per bug 6656139 it appears to be JVM 1.5.x limitation, because same
actions work fine when using SUN JRE 1.4.2_xx.
*** 07/17/08 07:31 am BUSINESS NEED ***
Impossible to run reports against two different databases simultaniously
using same Discoverer instace, or just several reports at the same time,
which would save much time instead of running reports one by one.

Error 'Unable To Connect Discoverer Server: Null' When Opening A Second Plus Session From The Same Browser [ID 790187.1]
Cause
Bug 6656139, JVM 1.5 : RUNNING TWO PLUS SESSIONS ERRORS WITH UNABLE TO CONNECT: NULL
The Java Console reports the following error:
Error: java.lang.StackOverflowError
java.lang.StackOverflowError
at java.awt.DefaultFocusTraversalPolicy.accept(Unknown Source)
at java.awt.ContainerOrderFocusTraversalPolicy.getFirstComponent(Unknown Source)
at java.awt.ContainerOrderFocusTraversalPolicy.getFirstComponent(Unknown Source)
at javax.swing.DefaultFocusManager.getFirstComponent(Unknown Source)
Per Bug 6656139 this problem is a limitation/bug with current Sun JRE 1.5
and higher and needs to be addressed by Sun.
Solution
Currently launching two Discoverer Plus sessions from the same browser connection page is not supported/certified.

Error in generating a new XSL Transformer from large xslt File
Good day to all,
Currently I am facing a problem that whenever i try generating a Transformer object from TransformerFactory, I will have a TransformerConfigurationException threw. I have did some research from the net and understand that it is due to a bug that JVM memory limit of 64kb. However is there any external package or project that has already addressed to this problem? I have checked apache but they already patch the problem in Xalan 2.7.1. However I couldn't find any release of 2.7.1
Please help
Regards
RollinMaoIf you have the transformation rules in a separate XSLT file, then, you can use com.icl.saxon package to get XML files transformed. I have used this package with large XSL files and has worked well.

ReentrantLock is missing wake signals resulting in a deadlock
We are hitting an issue with ReentrantLock where it is missing the awake signal resulting in a deadlock. Here is the thread dump for the same. As you can see, Thread-55 is blocked on acquiring the lock, which is not locked by any other thread. This issue is very similar to
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6822370 which happens in Sunspot JVM.

Open a ticket with support to file a BUG with JVM team.
Or try to upgrade your JVM to avoid this issue.
Regards,
Kal -
Hello all. I have quite a trouble with JVM:
We're developing a multimodule web application. Modified wars (=modules) are sent from continuous integration server to our development JBoss many times a day - this redeploys modified WAR. The same for clients - we'd like to redeploy single modules without restarting the server.
Unfortunately after few redeploys we get PermGen space. Server is useless and must be restarted.
1) When JVM started with -client option I can avoid PermGen space, but from time to time (~1/10 redeploys), I get this:
Cause: Class 'org.richfaces.renderkit.html.SuggestionBoxRenderer' is missing a runtime dependency: java.lang.NoClassDefFoundError: org/ajax4jsf/renderkit/compiler/ElementBase$1
at com.sun.faces.config.ConfigManager.initialize(ConfigManager.java:213)
at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:196)
at org.jboss.web.jsf.integration.config.JBossJSFConfigureListener.contextInitialized(JBossJSFConfigureListener.java:69)
I need to restart redeploy. After few redeploys this error repeats.
A bug in JVM or JBoss, or do I need to add some magical command line options for JVM?
2) With -server option I still have PermGen space, because JVM doesn't call finalize() methods on objects. Finalization queue is big.
Is there any JVM option for enabling finalization in -server mode (except manual calling System.runFinalization()), or this is a bug in JVM?
3) According to -XX:+TraceClassUnloading, JVM unloads unused classes only when PermGen memory is full. Lots of unused classes from WEB-INF/lib are kept in memory for long time. Couldn't this unloading be done earlier?
Any ideas? My JVM version is 1.6.0_10.And another thing I don't understand with -server option. Sometimes instead of throwing PermGen, the application is frozen by GC. But even weak references to some objects aren't removed, for example:
Class Name | Ref. Objects | Shallow Heap | Ref. Shallow Heap | Retained Heap
class java.lang.reflect.Proxy @ 0x3fd83b8 System Class | 1 | 40 | 120 | 58 504
'- loaderToCache java.util.WeakHashMap @ 0x8cf8ad8 | 1 | 48 | 120 | 41 312
'- table java.util.WeakHashMap$Entry[128] @ 0xa2e3fe8 | 1 | 528 | 120 | 41 232
'- [43] java.util.WeakHashMap$Entry @ 0xa9e0390 | 1 | 40 | 120 | 2 344
'- referent org.jboss.mx.loading.UnifiedClassLoader3 @ 0xa89a360| 1 | 120 | 120 | 1 636 912

Performance problem with synchronized singleton
I'm using the singleton pattern to cache incoming JMS Message data from a 3rd party. I'm seeing terrible performance though, and I think it's because I've misunderstood something.
My singleton class stores incoming JMS messages in a HashMap, so that successive messages can be checked to see if they are a new piece of data, or an update to an earlier one.
I followed the traditional examples of a private constructor and a public getInstance method, and applied the double-checked locking to the latter. However, a colleague then suggested that all my other methods in the same class should also be synchronized - is this the case or am I creating an unnecessary performance bottleneck? Or have I unwittingly created that bottleneck elsewhere?
package com.mycode;
import java.util.HashMap;
import java.util.Iterator;
public class DataCache {
private volatile static DataCache uniqueInstance;
private HashMap<String, DataCacheElement> dataCache;
private DataCache() {
if (dataCache == null) {
dataCache = new HashMap<String, DataCacheElement>();
public static DataCache getInstance() {
if (uniqueInstance == null) {
synchronized (DataCache.class) {
if (uniqueInstance == null) {
uniqueInstance = new DataCache();
return uniqueInstance;
public synchronized void put(String uniqueID, DataCacheElement dataCacheElement) {
dataCache.put(uniqueID, dataCacheElement);
public synchronized DataCacheElement get(String uniqueID) {
DataCacheElement dataCacheElement = (DataCacheElement) dataCache.get(uniqueID);
return dataCacheElement;
public synchronized void remove(String uniqueID) {
dataCache.remove(uniqueID);
public synchronized int getCacheSize() {
return dataCache.keySet().size();
* Flushes all objects from the cache that are older than the
* expiry time.
* @param expiryTime (long milliseconds)
public synchronized void flush(long expiryTime) {
String uniqueID;
long currentDate = System.currentTimeMillis();
long compareDate = currentDate - (expiryTime);
Iterator<String> iterator = dataCache.keySet().iterator();
while( iterator.hasNext() ){
// Get element by unique key
uniqueID = (String) iterator.next();
DataCacheElement dataCacheElement = (DataCacheElement) get(uniqueID);
// get time from element
long lastUpdatedDate = dataCacheElement.getUpdatedDate();
// if time is greater than 1 day, remove element from cache
if (lastUpdatedDate < compareDate) {
remove(uniqueID);
public synchronized void empty() {
dataCache.clear();

Which is broken. http://www.ibm.com/developerworks/java/library/j-dcl.html
from the link:
The theory behind double-checked locking is perfect. Unfortunately, reality is entirely different. The problem with double-checked locking is that there is no guarantee it will work on single or multi-processor machines.
The issue of the failure of double-checked locking is not due to implementation bugs in JVMs but to the current Java platform memory model. The memory model allows what is known as "out-of-order writes" and is a prime reason why this idiom fails[b].
I had a read of that article and have a couple of questions about it:
1. The article was written way back in May 2002 - is the issue they describe relevant to Java 6's memory model? DCL will work starting with 1.4 or 1.5, if you make the variable you're testing volatile. However, there's no reason to do it.
Lazy instantiation is almost never appropriate, and for those rare times when it is, use a nested class to hold your instance reference. (There are examples if you search for them.) I'd be willing to be lazy instantiation is no appropriate in your case, so you don't need to muck with syncing or DCL or any of that nonsense. -
ReportViewerBean popup dialogs not located correctly
When invoking ReportViewerBean.exportView, the confirmation dialog after export completion is located at the top-left of the screen. Is there a fix / workaround for this problem?
The same problem occurs when invoking the standard Export and Print buttons on the toolbar.I'm not aware of any recent bugs with JVM 1.6.x - there were some way back in 1.2/1.3.
The Print Dialog - it's the standard Java one - shouldn't be centered. The export dialog should.
Quick test - the ReportViewerBean is located in the CrystalReportsRuntime.jar.
Put all the 12.x jars in the classpath, and execute:
java com.crystaldecisions.ReportViewer.ReportViewerFrame
make sure the "Crystal Reports 2008" appears on the top right corner, then select "All Files" then a rpt with saved data.
Does the bare ReportViewerBean in a JFrame exibit the same behavior?
If so, then there's some issue with your environment.
If not, then I'd go to your project and introspect the JSwing hierarchy - there's something causing the parent frame location to be zeroed, from the JDialog perspective.
Sincerely,
Ted Ueda
