For allowing the caller maximal flexibility (and responsibility), BooleanQuery could interpret the maxint as a hint saying "maximal possible value" and then silently modify it to maxint-1, thereby avoiding the negative array size issue in PriorityQueue (and possibly fail later with out of memory). Is this what you have in mind? > FuzzyQuery produces a "java.lang.NegativeArraySizeException" in PriorityQueue.initialize if I use Integer.MAX_VALUE as BooleanQuery.MaxClauseCount > -------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: LUCENE-504 > URL: http://issues.apache.org/jira/browse/LUCENE-504 > Project: Lucene - Java > Type: Bug > Components: Search > Versions: 1.9 > Reporter: Joerg Henss > Priority: Minor > Attachments: BooleanQuery.java.diff, PriorityQueue.java.diff, TestFuzzyQueryError.java > > PriorityQueue creates an "java.lang.NegativeArraySizeException" when initialized with Integer.MAX_VALUE, because Integer overflows. I think this could be a general problem with PriorityQueue. The Error occured when I set BooleanQuery.MaxClauseCount to Integer.MAX_VALUE and user a FuzzyQuery for searching. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscribe@lucene.apache.org For additional commands, e-mail: java-dev-help@lucene.apache.org
