 I already talked about it when I asked about "Random
java.util.NoSuchElementException exceptions when using perfasm"
 back in january 2017.  I know this is probably not the right place to
ask but I don't have any better idea. I think it may be the same
crash, but it was so long ago that I'm not sure. I am able to
reproduce it only with JMH with perfasm on my project so far, and is
uses hsdis, which means it may not necessarily be JVM issue. And I'm
profiling the same code part of code (a big part of code) as back
then. The problematic frame I'm getting is "V  [libjvm.so+0x8e095d]
Monitor::lock_without_safepoint_check()+0x3d".

I'm not really sure where I should even report it. I just happened to
get a core dump from it so this is the first time I may have enough
information to actually report it somewhere.

Could I get some information as to what would be the appropriate place
to report it?
