This does not seem to happen with an oracle JRE. Not sure if anyone has seen this before. It does happen consistently.

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007fefa89110f4, pid=1363, tid=140666446931712

# Java VM: OpenJDK 64-Bit Server VM (25.66-b17 mixed mode linux-amd64 compressed oops)
# Problematic frame:

Hi panghy,
Thanks for letting us know about this issue. 

Would you be able to share your test case with us?

Hi Panghy, just checking in. We haven’t seen this crash before and we’re wondering if you can share a test case that would let us reproduce it.

Hi Panghy

Just checking if you got the chance to test with our latest version of Zulu which is Zulu 8.17 if this crash is reproducible? Would be really helpful if we had a testcase.
