LWJGL 2.1.0 VM crash

[erikd]

I just updated my game to use LWJGL 2.1.0, but I'm now getting a VM crash:

#
# An unexpected error has been detected by Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0b797f57, pid=2500, tid=3040

[error occurred during error reporting, step 270, id 0xc0000005]

It rather looks like this new LWJGL is causing my video drivers to crash, which the old version from LWJGL that I used didn't do.

I'm using:
WinXP SP3, java 1.6.0_13, Mobile Intel 945GM Express

Any idea?

Cheers,
Erik

Is it all LWJGL applications?
I get very similar errors, with the new LWJGL version, if the application terminates pre-maturely before a call to Display.destroy();

Have you tried launching with lwjgl debugger on (command line arguement -Dorg.lwjgl.util.Debug=true);
also maybe turn on trace logging in the java control panel, and check the sun/deployment/log files.

I don't know if it's all applications. Do you know another LWJGL 2.1.0 application somewhere that I can try?

Debug gave me this:

INIT COMPLETE

After initialization (which seemed to be successful, although the LWJGL debug log output seems a bit worrying), the line that causes the crash is this:

GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);

...which is a bit strange since the INIT already did the same successfully, and it's such a trivial thing...

I don't know if it's all applications. Do you know another LWJGL 2.1.0 application somewhere that I can try?

the demos over at http://www.lwjgl.org/demos.php should be using LWJGL 2.1.0

[erikd]

I also tested many other versions of LWJGL, and I only got the previous version that the game used to work (1.0 beta; yes I know, it's ancient  ). Other versions I tried (2.0.1, 2.0, 1.1.4) all caused the same VM crash here.

But... the demo's work fine here, so it's probably something I'm doing wrong (or at least there is a workaround) so there's hope...

[erikd]

I think I did something wrong in the initialization process. It's strange that it didn't crash in the old LWJGL, but in any case the problem is solved.

Please can you give us more details to allow us to have a quick fix to provide if someone else makes the same mistake?

When it crashed, I had this in the beginning of the initialization, before setting the display mode:

1   2

Display.setFullscreen(true);         Display.create();

I moved those lines to after setting the display mode
