Hi there!

This is my first post here. So I'll start with saying: Hello everyone!
Now to my problem:

On my Ubuntu-Machine the JVM crashes when I try to shutdown the OpenGL renderer.

This is what gets logged. (I tried to remove non-jpct-stuff, but I may have missed sth.)

Code Select
Java version is: 1.6.0_22
-> support for BufferedImage
Version helper for 1.5+ initialized!
-> using BufferedImage
Software renderer (OpenGL mode) initialized
Software renderer disposed
Can't find desired videomode (1024 x 768 x 32) - searching for alternatives
Can't find alternative videomode (1024 x 768 x 32) - trying something else
Current mode:1024 x 768 x 24 @75Hz
Software renderer disposed
Driver is: unknown OpenGL driver on ATI Technologies Inc. / ATI Radeon HD 4770
GL_ARB_texture_env_combine supported and used!
FBO supported and used!
OpenGL renderer initialized (using 4 texture stages)
[App specific logs...]
OpenGL renderer disposed

The initialization code looks about this:
Code Select

buffer = new FrameBuffer(1024, 768, FrameBuffer.SAMPLINGMODE_NORMAL);
buffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
buffer.enableRenderer(IRenderer.RENDERER_OPENGL, IRenderer.MODE_OPENGL);


The deinitialization code looks about this:
Code Select

buffer.disableRenderer(IRenderer.RENDERER_OPENGL);
buffer.dispose();

[...]

System.exit(0);


But the crash occures also, if the first two lines are commented out.
My best guess is, that the following System.exit() call has to kill some onliving threads.
If that is the case, how do can I wait for these threads to terminate? And why doesn't this
happen on my Win7 (32bit) machine?

The generated log:

There are no threads running at that time that were spawned by jPCT. You can easily see that when looking at the thread list of the dump. I noticed similar problems on some Windows based systems. It always helped to remove the dispose()-calls and rely on System.exit(0); alone to clean up the place.
In this case, this obviously isn't the problem. I'm a bit stuck here...which version of LWJGL are you using? Maybe an update/downdate helps?

I'm not sure about the version. So I replaced all jars (jpct and lwjgl) by those present in the currently loadable JPCT package.
No change regarding the error though. According to the folder name, it would be LWJGL 2.4.2.

Perhaps I should mention that this crash is perfectly reproducible here. It happens every time. If further information would be helpful, just say what you need.

I'm going to try the latest LWJGL version (2.6) as next step. And I will check, if the examples crash as well.
Concerning the downgrade: Any suggestions which version(s) is known to work / is recommended?
(I'd prefer to stay up to date. This is not an issue at "runtime". But if it helps to pinpoint the problem...)

Thanks for your time!

Upgrading LWJGL to version 2.6 fixed it.
Still, I think this is odd. If you're interested I'd provide any help I can to figure out what this is about.

I'm always curious about the why!

Thanks a lot!

Edit:
I was way to fast :-/
The crash probability went down. but it still happens.
Now trying the examples.

Ok, obviously the car & fps example use the software renderer.
The helloworld example however does crash.

run_opengl.sh & run_awtgl.sh produce the same crash. However, run_awtgl.sh seems to have trouble rendering at all.
The created window stays blank.

This indicates, that this is not a problem with my code. Maybe ATI cards are problematic? Unfortunately I don't have
any nvidia cards flying around to test it. Since this doesn't happen when booting windows, it seems to be a problem
either LWJGL or the graphics card driver (or even the Java distribution?).

This officially sucks ;-). I'll watch out for a workaround. But if you have any ideas left, let me know.

After digging  a bit around I found the following:

http://lwjgl.org/forum/index.php/topic,2350.0.html

and more interesting:
http://jogamp.762907.n3.nabble.com/SIGSEGV-when-closing-JOGL-applications-td895912.html

Post by Sven Gothel:
QuoteSo, we decided to 'ignore' this SEGV thingy until further investigation,
however, it has something to do with X11 and multithreading.

We use 'XInitThreads()' to setup X11 multithreading support
and it seems that the [J]AWT implementation in the JVM calls
X11 functions before and after JOGL runs.

The lack of calling 'XInitThreads()' in the JVM/JRE (when using AWT)
is already identified as a huge pain and a workaround for this
does not seem to be a good idea at all(*).

The best solution would be to convince Oracle/OpenJDK to issue
the XInitThread() call ASAP (before any other X11 call),
and to revisit some _global_ AWT locks, since they are probably no more necessary.
This would allow true inter-component multithreading with X11
without the need of a global AWT toolkit lock and hence
a fluent X11 workflow where threads won't disturb each other anymore.

BTW .. without XInitThreads() and with XLockDisplay
it was not possible with the NV driver to manage lifecycle operations
(create, makecurrent/release, destroy) in a reliable manner across threads.
Eg:
  thread1: createContext, makeCurrent, some-rendering, release ..
  thread1: stops
  thread2: makeCurrent/release, destroyContext
           -> hangs somewhere, ie makeCurrent, swapBuffer or destroy

So .. we have to think about this, and triage this in more detail.

Multithreading in JOGL is not about using multiple rendering threads
here, but to allow multiple threads to use the same X11 Display connection
for rendering and event dispatching undisturbed, read: non blocking.

For now, all I can say is, don't worry about this message,
it ain't even considered a failure/error with the junit tests.

So this is not a JPCT thing.
