A java's super Bug!
If you get a float number that larger than 999999999,
in java, you can't get the integer part of the number
and show it with String.
For Example:
Float largeF = new Float(999999999.222);
from 'largeF', you can not get a value of Long that equals 999999999,
and you can't get a string that is "999999999" use 'largeF' too.
In a word, in java, if a decimal fraction larger than 999999999, you can't get the decimal fraction's Integer.
Using java.math.BigDecimal solves this. This is actually a problem that most languages have because they limit the representation of basic types to set number of bytes. The reason for this is that it maps nicely to registers on the CPU and is faster.

Is the Java "Zero-Day" bug dangerous for MountainLion users?
Is the Java "Zero-Day" bug dangerous for MountainLion users?
It is not yet dangerous, to my knowledge, as it is currently being used only to distribute Windows malware. But users of Java 7 are certainly vulnerable, should a hacker start distributing Mac malware through this vulnerability.

My Java program crashes (on a Linux system) with the following log:
# An unexpected error has been detected by HotSpot Virtual Machine:
# SIGSEGV (0xb) at pc=0x4c949182, pid=2672, tid=2981530512
# Java VM: Java HotSpot(TM) Client VM (1.5.0_12-b04 mixed mode, sharing)
# Problematic frame:
# C [libc.so.6+0x68182]
Is this a bug in my Java code, JVM or the Linux system?
I am not sure, but i would say that any bug in my Java Code would give me an exception ERROR not a SIGSEGV.
As it is a segmentation fault error it probably is JVM or Linux?
Does anyone know?
//PaulHi!
From what i have seen in the err-logs the crash is always in libc. When i look into the stack trace i can see that
there has always been a malloc or calloc (2'nd or 3'rd pos in stack trace) just before the crash.
I run Fedora 7. But i have the same problem when trying it on FC8 too.
Here is the complete error log:
# An unexpected error has been detected by HotSpot Virtual Machine:

I think I'm being really dense here but for the life of me, I can't get this code to work properly. I am trying to build a NIO socket server using JDK 1.4.1-b21. I know about how the selector OP_WRITE functionality has changed and that isn't my problem. My problem is that when I run this code:
if (key.isAcceptable()) {
System.out.println("accept at " + System.currentTimeMillis());
socket = server.accept();
socket.configureBlocking(false);
socket.register(selector, SelectionKey.OP_READ | SelectionKey.OP_WRITE);
if (key.isWritable()) {
SocketChannel client = (SocketChannel)key.channel();
System.out.println("write at " + System.currentTimeMillis());
if (key.isReadable()) {
SocketChannel client = (SocketChannel)key.channel();
readBuffer.clear();
client.read(readBuffer);
System.out.println("read at " + System.currentTimeMillis());
}the isWritable if statement will always return (which is fine) and the isReadable if statement will NEVER return (which is most certainly NOT FINE!!). The readBuffer code is there just to clear out the read buffer so isReadable is only called once per data sent.
This SEEMS to be a bug in how the selector works? I would expect to see isReadable return true whenever data is sent, but that is not the case. Now here is the real kicker ;) Go ahead and change this line:
socket.register(selector, SelectionKey.OP_READ | SelectionKey.OP_WRITE);to this:socket.register(selector, SelectionKey.OP_READ);And now it appears that isReadable is running as expected?! To let people run this code on their own, I have uploaded a copy of the entire java file here:
http://www.electrotank.com/lab/personal/mike/NioTest.java
Please forgive the code, it's just the smallest test harness I could make and much of it is lifted from other posts on this forum. You can test this by using Telnet and connecting to 127.0.0.1:8080. You can test the isReadable piece by just typing in the Telnet window.
Someone else has listed something as a bug in the Bug Parade, but the test case is flawed:
http://developer.java.sun.com/developer/bugParade/bugs/4755720.html
If this does prove to be a bug, has someone listed this already? Is there a nice clean workaround? I'm getting really desperate here. This bug makes the NIO socket stuff pretty unusable. Thanks in advance for the help!!

Electrotank, Inc.Yeah, isReadable crashed for me too.
My solution was to not call it. I set up two selectors for the two operations I wanted notifying (accept and read) and used them independently in different threads. The accept thread passes them over to the read thread when they're accepted.
This way I don't need to call isReadable since it is bound to be readable otherwise it wouldn't have returned, as read is the only operation I'm being notified about.

Bad http.agent in Java properties : a bug in the HTTP user-agent string?
Hi all,
Me :
I'm patching AWSTATS (web log analyzer tool) in order to recognize which Java version has
been used to download files.
Context of the problem :
Each time a Java program (or applet) is downloading a file (for example .class, .png, .html)
from a web server, a line will be added in the web server log file. If the web server is well
configured, the user agent used to download the file will be at the end of the line in the log file.
For Sun Java JVM, the user agent string is configured in the Java properties under "http.agent".
Usually, the user-agent string contains the word "Java" and the virtual machine version. In most
cases, this is just a string like "Java/1.4.2", so this is relatively easy to parse.
Problem :
Looking in my web server stats, and then on the web, I found that a JVM's user-agent is
"Mozilla/4.0 (Windows XP 5.1)", which obviously does not contains the word "Java".
Consequently, it is difficult to say that this user-agent string belongs to a JVM.
Further look in my log files and on google shows that this http.agent string appears
on Microsoft Internet Explorer (it seems MSIE 6.0) over Windows XP with the J2RE plugin:

The J2RE plugin version does not seems to play a role as this user-agent string has
been seen on 1.4.1_02-b06, 1.4.2_01, 1.4.2_03 and 1.4.2_04-b05.
Further information requested :
I would like to know:
1) if you have reported the same problem;
2) if there is some rules for the http.agent property;
3) if this is a bug.
Thank you very much, and feel free to add you opinion.

Hi
All variable pass into a function, shuould passed by value, so we are not able to change the original variable through the parameter. But something wrong here:
import javax.swing.tree.DefaultMutableTreeNode;
public class tt{
public static void main(String[] args){
DefaultMutableTreeNode t=new DefaultMutableTreeNode("123");
ccc(t);
System.out.println(t.getUserObject());
static private void ccc(DefaultMutableTreeNode a){
a.setUserObject("456");
it should print 123, but it print 456. Should it be a bug of Java?
thanks from Peter ([email protected])u have not understood the concept of object references thats y u feel its wrong..be careful when u make such statements.
When objects are passed to functions, its the object reference thats getting passed, and obviously the reference is passed by value.but using this reference, the function can point to the actual object in the heap and if any change is made..it reflects the actual object.
here..object reference is passed by value which gets allocated in the functions stack and it points to the actual object which is allocated in the heap.
hope its clear..its not a bug..

I am not sure this is a bug, which is why I wanted to ask before I posted it. We have an applet that runs over the weekend, and on Monday morning is has died. The reason is the logging done to the console fills it up. Here is an example that will kill it quickly...
public class TestApplet extends JApplet {
public void start() {
Timer timer = new Timer();
timer.schedual( new TimerTask() {
public void run() {
for( int i = 0; i < 10000; ++i )
System.out.println("Logging Info");
}, 0, 10);
}I would not think that this would kill the web browser, but it does.
I'm using Java 5.0.4 and Windows XP SP1.
Is this a bug, or has this always behaved like this.On Windows at least, go to the Control Panel and click on the icon for the specific JRE you are trying to configure. In JRE 1.3, on the Basic tab there is checkbox for Show Java Console. If this box is checked, the console will pop-up when started. If it's not checked the Java System tray icon will appear only and you can access the console by doubling clicking on it.

JTable Java 1.6 Bug Progress ??? Work Around ?
I was just wondering if there was a work around for the following bug on java 1.6 ???
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6568959
This has been really annoying me because it's a requirement to use JInternalFrame and of course they want to treat the JTable like a spread sheet and edit cells using the keyboard and mouse. Is there some way to fix this really soon ? I was shocked why my program worked so well until I tried java 1.6 JRE and then the focus problems came.I was just wondering if there was a work around for the following bug on java 1.6 ???

Java Bean Serialization bugs (2 of them)
I have an EJB Primary Key with one public field - and I have hit 2 bugs trying to
serialize it to XML. I am currently running Weblogic 7.0.0.1 - the version that shipped
with Weblogic Platform last friday. I didnt have this problem with Weblogic 7.0 GA.
The problems are:
Bug 1) I have public JavaBean get/set methods for the field (its a string). The servicegen
ANT task throws an error because the field is both a property AND a public field
(though, there is no reason to do this according to the JAX-RPC spec)
The error I get is:
weblogic.xml.schema.binding.BindingException: Error: bean property and public field
found with the same name: starId
Bug 2) If I remove the get/set methods and regenerate (using servicegen again), it
fails at runtime because the generated code is looking for get/set methods (ie, it
is not accessing the public field directly).
The error I get is:
java.lang.NoSuchMethodError

Is this a known issue with the Weblogic Platform?
Do you know where I can find the release notes for weblogic platform?
Regards,
NickYes, i am able to reproduce both. I am not sure whether (1) is a bug though.
If the field is public and the class got get/set methods, it is not clear
whether
to access the value from the public field or by using the get/set method.
Get/set methods may have side effects and user may not see the expected
behavior. Anyway I will leave it to Scott to make the call.

TransformGestureEvent.GESTURE_SWIPE and Android: super bug?
I'm trying to make stuff with swipe event. I thought I was doing something very wrong but then I made a simple test and found out there's a really weird bug with either swipe events or with the android simulator (simcontroller) where I'm testing my applications. Basecally, if I add listeners to TransformGestureEvent.GESTURE_SWIPE in more then one eventDispatcher, after swiping over one of then the event is only triggered for that object for the rest of the execution. That happens if I use the simcontroller. However, if I play it on my Galaxy Tablet, it works just fine.
Here's the example of this behaviour. The code is in the Actions pannel.
http://www.4shared.com/file/hqLXR2Rs/Untitled-1.html?
steps:
- run the code with the simmulator
- select gesture - >swipe from touch and gesture tab of the simcontroller
- swipe inside one object
- swipe anywhere else
- run and select the swipe mode again
- swipe inside the other object
- swipe anywhere else
Please if someone has a solution for this let me know

Hi,
I am using jdk1.4.1
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)
I have a program run in background(use nohup ... &), It runes well under jdk1.3. But when I updated the jdk to 1.4, the program will shutdown randomly. What can I do? Thanks...the program will shutdown randomly.So there is absolutely no output of any kind? And no core file?
In the past when I have encountered this it was caused by one of two things.
Either something was eating an exception and not displaying anything before exiting.
Or System.exit() was being called. -
A new java.io.File does not get created.

File xslFOFile=new File("catalog.fo");

Result result = new StreamResult(xslFOFile);
transformer.transform(src, result);Error gets generated:

Mac/FireFox Java/JavaScript interaction bug
Hi,
I'm desperately trying to find a solution to a very platform-specific issue. Basically, I'm trying to get an applet to interact with the DOM of a web page. The basic procedure should be as follows:
1) Page loads
2) Applet loads
3) Applet reads in data file (as specified by parameter in object tag)
4) Applet sets title of document to contents of datafile
5) Applet sets flag to indicate that it's finished
6) Javascript checks flag regularly
7) When applet flag is set, JavaScript transfers the title to the body (using a div and changing the innerHTML property)
This works perfectly on most platforms (FF2/PC, FF3/PC, IE6/PC, IE7/PC, Safari/Mac) but for some reason FF/Mac isn't working. Or rather it is, but only about once per 50 attempts.
I had read that having an applet inside a <div> tag was a problem for FF/Mac, so I moved it outside, but it's still not working. Most of the time the applet is simply failing to set the title.
I'm using Eclipse for development, and the following libraries:
java.net.URL
org.w3c.dom.html.*
com.sun.java.browser.dom.*
The Java code in question is as follows:
DOMService serv = DOMService.getService (this);
dummy = (String) serv.invokeAndWait (new DOMAction () {public Object run (DOMAccessor accessor) {HTMLDocument website = (HTMLDocument)accessor.getDocument (FeedApplet.this); website.setTitle(docstring); return website.getTitle ();}});
Any help would be much appreciated - thanks!
AndrewThanks for your replies. Sorry for being a bit vague - it was an end-of-the-day-end-of-my-wits posting!
baftos, I've tried replacing the init() routine with a start() routine, but this hasn't changed anything. The problem appears to be with the Javascript timing, in that it's assuming the applet has finished before it has actually finished.
jschell, step 4 appears to be the one that's failing. The title isn't being changed, but usually the taskbar says that the applet has started (occasionally it comes up with a NullPointerException). The system just seems to wait for a long time and nothing happens.The Javascript checks every second to see if a $ symbol (which is effectively the trigger) has appeared in the title, and if so then it moves the contents of the page from the title to the holding div. The flag in the applet is reset on starting the applet, and accessed through a get-type method, so it shouldn't be cached.
It works in OmniWeb and Safari on a Mac, and IE/FF/Opera on a PC, so it's very specifically rooted in the FF/Mac problem zone. -
Don't know if there's a solution or if it's "just one of those things"...
But I started a project in PPro CS2, with lower third graphics created in AE with an alpha channel so they're self-keying. I had them fade in at the same time a directional blur effect was fading out.
I recently updated to PPro CS4. When I opened this project in CS4, the lower third fades in okay, but at the point the blur reaches 0, the entire graphic jumps down a few lines.
I tried using a different type of blur, but it still jumps.
I tried reinserting the lower third and adding the fade in and blur fresh - but it still happens. To make sure it wasn't just the monitoring, I exported the section and the jump is definitely there.
It works okay without the blur, so I may have to settle for that.
Any suggestions? I just thought - I'll try reimporting the graphic, and also double check the alpha channels settings are correct...There are a few bugs crawling around some of the filters in CS4 under certain conditions. Try adding an opacity keyframe to the clips set to 100%. it wont affect the effect, but this sometimes makes other filters behave.
