What is the possible reason for an EXCEPTION_ACCESS_VIOLATION crash?

I get this crash report when I run java bean of my project using eclipse. I have totally no idea what it is and how to debug. Can anyone tell me the possible way to debug this?

It means the JVM is crashing. Not much you can do to debug this, really, short of looking for a patch for the problem.

I'm pretty sure that version "1.6.0-b105" denotes the very first release (or one of the very first) of Java6, though. That's pretty old already.

I strongly suggest you upgrade to the current version (1.6.0_23, at time of writing this). This will very likely resolve your problem.
