Subject [jira] [Commented] (LUCENE-6725) Reindex crashes the JVM
Date Fri, 07 Aug 2015 09:58:45 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-6725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14661573#comment-14661573
] 

Jan Eerdekens commented on LUCENE-6725:
---------------------------------------

A next batch of results, still for 3.5 (newer is next): on 7u80 I still get the same crashes,
but on 8u51 all the tests succeed and I see no crashes. It is really starting to look like
a JVM issue (and probably really specific to Solaris/SPARC). A JVM upgrade is an option, albeit
that JDK8 is only 'supported' by Liferay EE, but not 'certified' yet.

I'll try to do some tests with Lucene 4.10 and maybe also already try to start Liferay with
the JDK8 version and see how it behaves.

> 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
