that tx should be associated with one of your clients. So if you cycle
your clients, it should get rolledback.
I know we now (5.8/9) track a range of data files associated with a
transaction so that gc is not blocked any more than it needs be. in
5.7 any later log file needs to remain.
see: https://issues.apache.org/jira/browse/AMQ-4262
