Some information you might have provided before being asked... which version of LWJGL is this? Is it reproducible always? Does it occur with any other versions?

Cas

[Wolftein]

Oh sry i forgot .

1 of 5 pc works fine.
4 of 5 pc i always get this error. I Believe that with other version the error is reproduced too.

LWJGL Version: 2.3
Opengl Version: 2.1.8543 Release

[Wolftein]

Well my bad, i fixed it . My AL.destroy(); is in the class finalizer and java wasn't calling it, so i put a .gc() to force it.

[princec]

Arrgh! Never use finalizers!

Cas

[kappa]

Arrgh! Never use finalizers!

Cas

huh? just curious as to why you'd say that?

[Matzon]

Arrgh! Never use finalizers!

+1 to Cas

finalizers are unpredictable and will only be called when you gc'ing occurs. If you make a mess - clean up yourself, don't rely on someone else.

[princec]

Not even then! They occur at an indeterminate random future point, after GC has cleared the last reference away!

The mechanism you are looking for is ReferenceQueues.

Not even then! They occur at an indeterminate random future point, after GC has cleared the last reference away!

Personally, I can recommend to use finalizers as a backup unload mechanism for stuff that has a OpenGL counterpart. VBO's, Textures and Shaders for example.

In my engine, if finalize() is called, it checks if the resource is still loaded in OpenGL (handle > 0). If so, it adds the handle to a list with garbage collected buffers or whatever the resource is. The Renderer checks the lists before drawing a scene and if there is anything in it, it unloads the resources. Unloading can't be done in finalize() because it needs to be done on the OpenGL Thread.

In this way leaking resources is less likely. Of course, it is still advisable to unload the resources yourself because of the unpredictable nature of finalization.
