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

> 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.
