Florian Waltersdorfer commented on LUCENE-504:
----------------------------------------------

Hi,

something along the line of
ScoreDoc[] results = searcher.search(query, MAX_NUMBER_OF_HITS).scoreDocs;
causes a viable crash. I would consider this a "natural" start when trying to write an own searcher (MAX_NUMBER_OF_HITS beeing Integer.MAX_VALUE) and without the sources attached & the (eclipse) debugger I would have never found the problem I'd guess.
So please do something about this pitfall, if only adding a warning in the javadoc of i.e. Searcher.search(..., int n, ...)

Thanks
Florian
FuzzyQuery produces a "java.lang.NegativeArraySizeException" in PriorityQueue.initialize if I use Integer.MAX_VALUE as BooleanQuery.MaxClauseCount

Key: LUCENE-504
URL: https://issues.apache.org/jira/browse/LUCENE-504
Project: Lucene - Java
Issue Type: Bug
Components: Search
Affects Versions: 1.9
Reporter: Joerg Henss
Priority: Minor
Attachments: BooleanQuery.java.diff, fuzzyquery.patch, 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.
