Bug 4829458 is fixed in the next release.
After investigation we found that bug 4836337 is ATI driver problem so this is closed.
Runing same test program on Nvidia Quadra4 and our own frame buffer - both support 4 multitexture in a single pass, doesn't show crash when exit.
We also have a multitexture program which show texture mess up when using display list after texture stage changes under Radeon 9700. All go through the same code path.
ATI use to have better DirectX driver than OpenGL. We try your applications on DirectX version of Java3D. At first the texture is rendered as black color. This is due to missing normal in the rectangular shape. Unlike OGL, D3D probably require this in order for certain texture mode (like MODULATE) to work.
After adding normal your application run fine without crash on exit.
