        Description

        The attached test crashes on JDK 8u40 and JDK 8u60b11.

        Steps to reproduce:
        1. Unpack the attached project
        2. Run "mvn test".

        It may be necessary to run it several times before seeing the crash. On:
        Linux lahvacovo 3.16.0-31-generic #41-Ubuntu SMP Tue Feb 10 15:24:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
        with 4 cores, approximately 1 of 10 runs crashes.

        It was reported the probability of the crashes depends on the number of cores - with 8 cores, the crash is said to be more likely.

        Attached is the test project and hs_err*log files for JDK8u40 and JDK8u60. I can provide core files, if desired.

        This appears to be similar to JDK-8059529, but the bug described herein was not seen on JDK8u20.
