[jira] Updated: (LUCENE-543) Wildcard query with no wildcard
characters in the term throws StringIndexOutOfBounds exception
[ http://issues.apache.org/jira/browse/LUCENE-543?page=all ]
Michael Busch updated LUCENE-543:
---------------------------------
Attachment: lucene543.patch
Overwrites rewrite() in WildcardQuery so that it returns a TermQuery if and only if the term does not contain a wildcard character. I also added a new test to TestWildcard that fails with the old version and passes with the patch.
All units tests pass and the patch compiles with a 1.4 JVM ;-)

> seems like a reasonable change to make, such that a WildcardQuery
> without a wildcard character would behave like TermQuery.
