Finalizer Thread - java.lang.rOperating System

Can anyone please help me understand what is being
conveyed by the finalizer portion of a thread dump:
"Finalizer" (TID:0x1669320, sys_thread_t:0x592180,
state:CW, native ID:0xe6) prio=8
at java.lang.Object.wait(Native Method)
at
java.lang.ref.ReferenceQueue.remove(ReferenceQueue.jav
, Compiled Code)
at java.lang.rOperating System: Windows NT Version
4.0
I have been unsuccessful in finding any information on
how java.lang.rOperating System comes into play. When
our finalizer thread looks like this within the thread
dump, the Reference Handler and Signal Dispatcher
threads do not appear at all within the dump. The
thread dump is from a web application using JRun with
IIS serving the web pages.
Thanks,
KimThis portion of the thread dump is corrupted. The finalizer thread dump should normally look something this assuming you didn't catch it in the middle of things:
"Finalizer" daemon prio=8 tid=0xe1010 nid=0x7 waiting on monitor [0xfdd81000..0xfdd819e0]
     at java.lang.Object.wait(Native Method)
     at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:149)
     at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:164)
     at java.lang.ref.Finalizer$FinalizerWorker$FinalizerThread.run(Finalizer.java:120)
Which version of Java are you running? (use java -version)

You've got to have the WebLogic JAR that contains the necessary .class files in your CLASSPATH when you run.
Don't use a CLASSPATH environment variable; use the -classpath option when you run.

I can not see main class weblogic.jar file in your class path.
Under MW_HOME there is a file by name configure.cmd/sh, run it to set acl and class path. Then try to start weblogic server. U can edit the startWeblogic.sh/cmd so that every time it will execute after calling configure.sh/cmd file.

Hi,
I have an application jar file which is run from a .sh file.
The application uses ridc api to checkin a document on UCM.
I have placed jars for supporting the application on the folder where we have kept the application jar
also we have mentioned the supporting jar file names in the Manifest.mf file of the application jar.
The necessary jar files which we have placed are:
com.lnt.ucm.integrationutility.ucm.Client
log4j-1.2.16.jar
oracle.ucm.ridc-11.1.1.jar
poi-2.5.1.jar

jrf.jar
org.eclipse.persistence_1.1.0.0_2-1.jar
weblogic.jar
wlfullclient.jar
wseeclient.jar
jaxws-rt-2.1.4.jar
we are getting below exception when we run the jar from the .sh file.

I am instantiating a MQQueue object..... When I run
the memory debugger it says a call is made to the
Finalizer.register method and the FInalizer object is
on heap even after the GC...Why is this a problem? If it is a problem again
1) Consult the bug database
2) Post formatted code that reproduces your problem.
Other than that consult these

This is the best and only advice I can give you based on your problem description.

Again you need to make a difference between what runs within the weblogic container to what runs in a vanilla JVM. Understanding this is crucial to your problem.
1. web service -> client -> another web service
The webservice will always run within the weblogic container and you should never get the ClassnotFound because weblogic.jar is always available there. Any subsequent clients loaded into the same JVM will presumably be in the same classloader and wont have problems either
2. client -> web service;
If you are using a standalone client in a JVM you shouldnt have any dependency on weblogic and commons-httpclient will work just fine as would commons-logging. However if you include some weblogic jars in the classpath, when you launch the client JVM you would need to include the jars mentioned in the other post because they reference other weblogic classes. But this isn't necessary if you just clean up your classpath to only have the jars you need.

Synchronizing unrelated threads - java.lang.IllegalMonitorStateException

Hi,
I'm trying to synchronize two unrelated threads using a third object, but getting java.lang.IllegalMonitorStateException: current thread not owner error. Does any one know what am I doing wrong and how to fix it. A simulated code is posted below.
Thanks in advance.
// ----------- beginning of code --------------------------
// Code that throws java.lang.IllegalMonitorStateException: current thread not owner error.
public class ThreadTest
public static void log( String message )
     System.out.println( Thread.currentThread().getName() + ":" + message );
public static void main( String args[] )
     Thread thread1 = new Thread1();
     Thread thread2 = new Thread2();
     thread1.start();
     thread2.start();
     try
     thread1.join();
     thread2.join();
     catch (InterruptedException e)
     e.printStackTrace();
     log( "All Done...");
class Thread1 extends Thread
public void run()
     synchronized( Common.done )
     while (!Common.done.booleanValue())
          ThreadTest.log("Waiting on Common.done");
          try
          Common.done.wait();
          catch (InterruptedException e)
          e.printStackTrace();
class Thread2 extends Thread
public void run()
     synchronized( Common.done )
     ThreadTest.log( "Sleeping for 10 seconds ");
     try
          Thread.sleep( 10 * 1000 );
     catch (InterruptedException e)
          e.printStackTrace();
     ThreadTest.log( "Calling notifyAll");
     Common.done = Boolean.TRUE;
     // ******* Why am I getting 'java.lang.IllegalMonitorStateException: current thread not owner' in the next line
     Common.done.notifyAll();
class Common
public static Boolean done = Boolean.FALSE;
// ----------- end of code --------------------------

// ******* Why am I getting'java.lang.IllegalMonitorStateException:
current thread not owner' in the next line
Common.done.notifyAll(); Because x.notifyAll() has to be inside a
synchronized(x) block.
The code you posted looks like it meets that
criteria, so I would have to conclude the code you
posted does not represent the actual code you are
running.Hi.. It is inside synchronized( Common.done) block... Thats why I'm confused....

The above mentioned is coming several times , anybody please help out to get rid of this issue.
Thanks in advance ,
Krikar.

This only tells you that the JVM is running out of heap space. It doesn't tell you what is causing the problem. You likely have a memory leak, but you could also try increasing the max heap size of the JVM (-Xmx command line option). It would help to watch the % mem in use statistic, but only immediately after a garbage collection cycle (you can force a GC from the admin console). If the % mem in use after the GC is increasing over time, then that likely confirms you have a memory leak. Note that looking at that statistic during the server startup probably is irrelevant. You'd need to wait until the server finishes starting up, and likely processed a few messages (to load static data).
If you get to the point of confirming that you have a memory leak, that requires doing detailed analysis with a Java profiler (JProfiler, JProbe, YourKit, etc.) to track down the source of the leak.

Java.lang.OutOfMemoryError: getNewTla in coherence production cluster!

Hi guys, we need some urgent help, JVMs in our production coherence cluster would randomly stop due to the outofmemory error, and we cannot find out the root cause.
1) Version 3.7.1.4, running 4x servers, each with 40x jvm, each jvm set to 2GB heap, for a total of 320GB cluster. Each server also has a extend proxy running with 3GB heap (no issue)
2) The cluster is configured using WKA by explicitly listing out all the server nodes in the config.
3) Our data storage is only ~30GB, details below.
Stats for cache 'CACHE0':
Number of cache entries: 14761116
Memory usage (mb): 26722.643
Average entry size (bytes): 1898

Grand total: 26775.413 MB, Number of entries: 14807237
4) Random jvms storage nodes (not proxy) on each server would just go down with below errors, we cannot reproduce the issue, it just happens at random. Out of 40 jvms on each server about 3-5 went down over the weekend on, the issue happens on all 4 servers.

5) Initially we thought it was because of a issue with the small default packet speaker size when joinining the nodes since we using WKA. But changing the config did not help:
<coherence>
<cluster-config>
<packet-speaker>
<volume-threshold>
<minimum-packets>10000</minimum-packets>
</volume-threshold>
</packet-speaker>
</cluster-config>
</coherence>
Out of ideas, any help will be greatly appreciated. Thanks

i dont think the issue is with the code, i just noticed as soon as i start up all the cache servers, 1 went down already. And noone is accessing the system.
this is extremely troublesome, i am loading the hprof file to look at the dump per suggestion above, not sure if it will help pinpoint the root cause though.

Simple JPA prog weblogic 10.3, struggling with java.lang.NoClassDef s

Hi,
Trying to run a basic JPA program using createEntityManagerFactory, EntityManager and persistence.xml.....Everything compiling fine. I'm running it as a standalone Java application on Weblogic 10.3. First I got this error on running.
Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/kernel/KernelLogManager, after that I did some search on the net and created the wlfullclient.jar and included it. After that I'm getting the below error.
Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/logging/LogEntryFormatter.
Tried removing wlcommons-logging.jar whenever facing an issue, but it doesnt help, it gives some other error when it is removed.
Can some one help to rectify this error please. Not able to find the jar file that has this class
Thanks,
Vick.

For folks who are struggling with this error, I'm posting the solution.
When you face this error java.lang.NoClassDefFoundError: weblogic/kernel/KernelLogManager, first remove the weblogic system libraries, then generate the wlfullclient.jar file(steps are in the net) and add it to classpath.
Ultimately after several inclusion of other jar files which wasnt included, it worked.
All the best.

Problem in java.lang.String.format()

Dear Experts,
I tried to display a double value with leading spaces with the following statements:
double val = 123456789.987654321;
System.out.println( String.format("%17.2f", val));They worked in void main(), but didn't in a method of a class. The following error message was found while compiling:
init:
deps-jar:
Compiling 1 source file to C:\JavaProject\ALC-EJB\build\jar
C:\JavaProject\ALC-EJB\src\java\escis\creditControl\BalanceRecord.java:61: cannot find symbol

location: class java.lang.String
System.out.println( String.format("%17.2f", val));

Not sure if this has got anything to do with it, but
the format() method was added to String in Java 5.0.
Maybe you are using an older version in that second
case?You're right. It works when I've changed it from 1.4 (default) to 1.5. Thank you very much.
