    # SIGSEGV (0xb)
    Almost always caused by JNI code or 3rd party libraries that use JNI.

    Hi Vitaly,

    Did you make any progress on the jvm crash you encountered? We seem to have the same crash as well. Looks like the GC thread is to blame.

    Anyone else got any idea?

    Cheers,
    Stefan
