Robert Muir commented on LUCENE-5532: ------------------------------------- Rethrow is good: I'll use that! > AutomatonQuery.hashCode is not thread safe > ------------------------------------------ > > Key: LUCENE-5532 > URL: https://issues.apache.org/jira/browse/LUCENE-5532 > Project: Lucene - Core > Issue Type: Bug > Reporter: Robert Muir > Attachments: LUCENE-5532.patch, LUCENE-5532.patch > > > This hashCode is implemented based on #states and #transitions. > These methods use getNumberedStates() though, which may oversize itself > during construction and then "size down" when its done. But numberedStates is > prematurely set (before its "ready"), which can cause a hashCode call from > another thread to see a corrupt state... causing things like NPEs from null > states and other strangeness. I don't think we should set this variable until > its "finished". -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
