Bug Description

The last 3 errors all look like this (pids being different of course). All mention nmethod.cpp line 1836, JavaThread "AWT-EventQueue-1", and libjvm.so. I can't deliberately reproduce the error but if I run netbeans for long enough it will crash.

I'm also having this problem, but with JOSM instead of Netbeans. I don't know how to reproduce, it simply happens when I've been modifying a map for a while. It seems like the chances of a crash increases with the number of modifications.

Same error message with PCGen 5.16.1, Kubuntu Jaunty amd64.
1. Run PCGen using pcgen.sh
2. Load default dataset, close Tip of the Day, click through the license screen
3. Click File -> New
4. Count to three

It crashes a few seconds after the New page opens, with the following information.

It's happened three times in the same way now; crash report #3 is attached.

Unfortunately I don't have time to do more thorough research, but I'll write my experiences here in case they help someone.

I had problems with frequent NetBeans crashes. It sometimes happened with refactoring, bookmarks or other "advanced" editor features, but most often it happend with form designer. It wasn't deterministic, ie. loading project after crash and doing it again would usually not crash again. And I sure learned to automatically do "save all" after every form change, after losing a bit of work a few times...

This happened with Jaunty's NetBeans 6.5, manually installed NetBeans 6.7.1 and now with Karmic's NetBeans 6.7.1 too, and this week it got so frequent that I had to do something about it (note: more frequent crashing was probably because of growing code size and complexity, not because of Jauntu -> Karmic update).

I solved the problem by removing openjdk-6 packages (not probably necessary) and using sun-java6. Not a single crash after that. I'm sorry I can't provide any technical information about the crashes, but it was so frequent that just doing some complex form design stuff with netbeans should trigger it.

Note: to get netbeans to use sun-java6 I had to manually edit /etc/netbeans.conf:
- netbeans_jdkhome="/usr/lib/jvm/java-6-openjdk"
+ netbeans_jdkhome="/usr/lib/jvm/java-6-sun"
I don't know if there's a way to do that automatically, but I think dpkg-reconfigure netbeans should maybe do it, if sun's jdk is installed and openjdk is not.

I also have frequent crashes with NetBeans. In several, at first glance random, moments. I just found a consistent way to reproduce a crash. This is what I explain next.

Steps to reproduce:
1. Open NetBeans
2. Right-click on a project in the project browser
3. Click "Properties", a windows titled "Project Properties" will appear
4. Resize that window during a couple a couple of seconds ()

What should happen: The "Project Properties" window gets resized.

What happens now: NetBeans crashes. If I start it from console (simply typing "netbeans"), on crashing some output appears: "
The program '<unknown>' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 18972 error_code 8 request_code 140 minor_code 4)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

This also happens to me, but only with metacity? I have no problems with compiz.

Getting the same error as #5 when resizing, not just with NetBeans but with several swing apps, i.e. TV-Browser, JDownloader, ArgoUML and some swing apps written by myself. However, when I tried the resizing on Geogebra it did not crash. This helped me (hopefully) pinpointing the problem.

All of the crashing applications allow you to set the look and feel to GTK l&f or have this as the default and only option. Geogebra, which does not crash, uses the default ocean l&f. So I configured JDownloader of them to use a different l&f and in fact, the crashes did stop. To workaroung the error, you can either avoid using GTK look, recompile the app and remove the code affecting the look and feel or use the Java distribution from Sun.

Also, this problem is not limited to resizing a window. I tried to create an app that can demonstrate this error but unfortunately the l&f is not the only factor responsible for the problem. Once I find the exact source, I will post the code here.

I hope this can help you guys to fix this problem. I have had this error for months now but I blamed the application for it.

same problem here.

It happens randomly, albeit it seems as though dragging and dropping editor tabs is very likely to make Netbeans crash.

is this reproducible with the packaged netbeans in ubuntu lucid?

I can't reproduce this bug in lucid

I'm seeing two or more crashes over an eight hour day on Lucid Beta 1. No apport recognition. Just disappears. Last time was during a macro operation. Once during a PHP web debug. Another time just editing.

I'm not able to reproduce the crash, because netbeans seems to crash randomly.

I was having stability problems in netbeans under Lucid. I resolved it by installing the sun jdk. Netbeans has been rock solid since. Not sure what the difference is between the two stacks. Would like to figure it out, tho.

This problem started manifesting on my machine within the last few weeks, using Open JDK and either Eclipse or the Maven Jetty runtime. I'm now encountering this problem several times a day.

Here's a somewhat recent crash report with latest netbeans version (7.0) on xubuntu natty. Same stability problems, it crashes randomly and very often so i was forced to change to sun/oracle jdk.

Getting the same stability problems with jMonkeyEngine (a repackaged Netbeans) on a 64-bit Oneiric.

Product Version: jMonkeyEngine SDK 3.0beta
Java: 1.6.0_23; OpenJDK 64-Bit Server VM 20.0-b11
System: Linux version 3.0.0-15-generic running on amd64; UTF-8; de_DE (jmonkeyplatform)

I haven't tried with the Sun SDK yet.
Since this affects more than one application, I blame either openjdk or the GTK theme, not the application itself.

Okay, my crash seems to be related to the nvidia driver, and inside the LWJGL thread (LWJGL is an OpenGL wrapper library).
It's still some X problem though, so I'm logging the crash report here anyway.
