There is no way a Java bug can crash the VM by itself. You can hit either a real VM bug or a bug in native code used by the VM.

So you have one or more
1) A broken Windows installation (some might consider this an tautology).
2) A corrupt JRE installation. Reinstall and see if things works better
3) A corrupt Eclipse. Try a fresh Eclipse.
4) Bad hardward, memory, malware leading to broken files (1).

2 & 3 are easy to test. If reinstalling the JRE doesn't help, try t he newest JRE available from SUN and see, Sun JVM bug reports should go to SUN. We will do absolutely nothing with them, though it would be interesting to get the ticket id when it gets assigned one.
