Subject activemq git commit: https://issues.apache.org/jira/browse/AMQ-5748
Date Sat, 08 Aug 2015 18:00:08 GMT
Repository: activemq
Updated Branches:
  refs/heads/master a3c8bee1f -> a49d46e3c


https://issues.apache.org/jira/browse/AMQ-5748

Updating MemoryTopicMessageStore to decrement store statistics on cache
eviction.  Updating KahaDBMessageStoreSizeStatTest to account for the
fact that a LRU cache is used so the last 100 messages are kept in
memroy.
