Mark Harwood 37a060c15c Additional thread safety around filter creation - old code could create duplicate CachingWrapperFilter if thread1 gets cache miss and thread 2 has a cache miss before thread1 populates cache with new CachingWrapperFilter. 
Synchronization cost around whole method is OK here because Filter object construction should be a lightweight call. 
Note: CachingWrapperFilter currently has a similar bug in bits() method but adding "synchronized" around that whole method would not be a solution there because of the cost of evaluating filter.bits and the unnecessary blocking effect this would have on threads using different readers to the thread with the lock.

INTRODUCTION

Lucene is a Java full-text search engine.  Lucene is not a complete
application, but rather a code library and API that can easily be used
to add search capabilities to applications.

The Lucene web site is at:
  http://lucene.apache.org/

Please join the Lucene-User mailing list by sending a message to:
  java-user-subscribe@lucene.apache.org
