Subject Re: Transaction not started XA problems

Enable trace level logging for ActiveMQ
org.apache.activemq.transaction.XATransaction to see when the rollback
is occurring. It seems that it is occurring before the TM attempts it,
possibly as a result of returning to a pool, which would point to a
bug or misconfiguration.

I suspect the 10 threads are the result of transaction completion on
each of the polling requests from the DMLC, it creates a new
session/consumer and will not get any message but will do a rollback.

I made some updates to better support recovery and exactly once
delivery semantics, see:
https://issues.apache.org/jira/browse/AMQ-3305 - to pick these up you
will need to use a 5.6-SNAPSHOT.
The test case uses geronimo from camel, but may provide a working use
case that you can compare and contrast with.
