I\'ve seen this question and this article on how to debug a native Java crash. The article is with respect to Windows. What are the equivalent debugging aids on Linux?
I was expecting a JNI call in the crash dump, but it does not appear to be the cause, but instead a bug in the pthreads library.
I cannot remember offhand if the pthreads library must be provided by the underlying platform or it is baked into the JRE, but I would suggest that you ensure that you are running on one of the officially supported Linux platforms and if not, then strongly consider switching.
