Help me with crash report, please

[Mikael Gerdin]

Hi Andrew,
I was able to decode the jvm.dll stack trace using an internal tool and 
it appears that you're crashing in DefNewGeneration::copy_to_survivor_space
and coming from GenCollectorPolicy::satisfy_failed_allocation (a few 
frames up).

This suggests that the VM is performing a GC and has come across a java 
object that has been tampered with somehow. It is likely that you've 
caused this using Unsafe (that's why it's called Unsafe :).
The VM tries to follow pointers at the "header" of a java object and if 
somebody has inadvertently written over an object with other data 
dereferencing that pointer will crash the VM.

The reason that it's not crashing in your thread is that the VM runs 
garbage collections on separate threads.

Regards
Mikael Gerdin
