Subject [jira] [Comment Edited] (LUCENE-6725) Reindex crashes the JVM

---------------------------------------------------------------

I would suggest to update to Java 8u51. I have an instance of Liferay (recent version) running
in production with Java 8. This performs much better (faster), maybe that also solves the
issue.

Alternatively use Java 7u80.

In General, I am thinking about installing a VM with OpenSolaris on Policeman Jenkins (http://jenkins.thetaphi.de),
but this bug may also be related to SPARC platform... SPARC is much more sensible to unaligned
accesses to memory and SIGSEGV/SIGBUS earlier. But this is a problem with Oracle's JDK.

> We're using Liferay which uses Lucene behind the screens to index things like documents,
web content, users, etc... . When we trigger a full reindex via the Liferay Control Panel,
which uses IndexWriter.deleteAll(), the JVM crashes and generates a dump with the following
message: 
> #
> # A fatal error has been detected by the Java Runtime Environment:
> #
> #  SIGSEGV (0xb) at pc=0xffffffff78de94a8, pid=18938, tid=2478
