------------------------------------------

             Summary: SpecialOperations.isFinite hits StackOverflowError on automaton accepting
long strings
                 Key: LUCENE-5659
                 URL: https://issues.apache.org/jira/browse/LUCENE-5659
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: 4.9, 5.0
         Attachments: LUCENE-5659.patch

Just like we fixed getFiniteStrings to not consume stack in proportion to the longest string
accepted by the automaton (LUCENE-5628), isFinite has the same limitation.  The fix is pretty
simple; I just share the code from getFiniteStrings, but allocate two BitSets up front like
the current impl.
