Subject [jira] Commented: (LUCENE-504) FuzzyQuery produces a "java.lang.NegativeArraySizeException" in PriorityQueue.initialize if I use Integer.MAX_VALUE as BooleanQuery.MaxClauseCount

Doron Cohen commented on LUCENE-504:
------------------------------------

I think it makes sense to separate here between efficiency and correctness.

The proposed fix above deals with efficiency, and maybe it should become a new separate future
issue, perhaps also considering a more lazy allocation of space by PriorityQueue.

This issue is about correctness - setting max-clause "by-the-book" throws an exception - let's
fix just that..

Modifying PriorityQueue to be tolerant to maxint capacity is one possible solution, though
perhaps an overkill.  

A simpler way is for PriorityQueue to silently decrement its maxsize by 1 in case maxsize
is requested to be maxint.

> 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.
