Subject: JVM crashes when textures are loaded????
JVM occasionally crashes with the error message below. The JVM crashes about one time out of ten executions. I place a snippet of code below, hopping someone could give me a clue.
- I have have the latest drivers.
- I am using the OpenGL version of Java3D.
- It does not appear to be a memory leak.
- All the files are present.
- The program do not crash on every execution.
What is all this stuff below I am not using any of it?
