Yonik Seeley updated LUCENE-1346:
---------------------------------

    Attachment: LUCENE-1346.patch

Attaching patch that changes Vector to ArrayList in PhraseQuery, MultiPhraseQuery, and in BooleanQuery.Weight.

I doubt there was ever any intent for these query classes to be partially thread safe.

> Replace Vector with ArrayList in Queries.  This can make a difference in heavily concurrent scenarios when Query objects are examined or compared (e.g. used as cache keys).
