Uwe Schindler updated LUCENE-7032: ---------------------------------- Labels: Java9 (was: ) > jdk-9-ea+105 breaks MinimizeOperations.minimize() > ------------------------------------------------- > > Key: LUCENE-7032 > URL: https://issues.apache.org/jira/browse/LUCENE-7032 > Project: Lucene - Core > Issue Type: Bug > Affects Versions: master > Reporter: Robert Muir > Labels: Java9 > > As soon as jdk-9-ea+105 was put into test rotation, automaton tests have been > sporatically failing in non-reproducible ways. All of them invoke hopcroft > minimization either directly or indirectly. > The bug manifests in several forms: > * ArrayIndexOutOfBoundsException in minimize() > * IllegalArgumentException for an explicit bounds check > * incorrect resulting automaton > This method is ... let's say not the ideal one to debug something like this, > but I've at least got it where I can make it fail in a few minutes with > beasting, so we can try simple things like turning on/off jvm flags to try to > narrow it more. > It would be really great to make it fail more efficiently, but unfortunately > it takes many thousands of iterations until we understand more about it. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
