RFR(S): 8134468: Lucene test failures with 32 bit JDK 9b78, Server compiler

[Roland Westrelin]

Uwe,

> Thanks. I was trying b82 yesterday and we already found a new bug. Tests were failing with SIGSEGV on Jenkins:
> http://jenkins.thetaphi.de/job/Lucene-Solr-5.x-Linux/14121/
> (you can download "hs_err" and "replay" from there, you can also see JVM settings like bitness, Garbage Collector from there).

Thanks for reporting this new issue.

> This happened in parallel for 2 different JVMs (we are running tests in parallel with multiple JVMs). We should look into this, too! Tell me how I can help (as always, it is hard to reproduce). So this must be some change between b78 and b82 (b78 is last known working config). Maybe bells are ringing for you.

It looks like it could be:

https://bugs.openjdk.java.net/browse/JDK-8134974

Can you reproduce the issue at all?

Roland.
