session.rollback() deadlocks
[ https://issues.apache.org/jira/browse/QPID-3911?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robbie Gemmell resolved QPID-3911.
----------------------------------
Resolution: Fixed
Fix Version/s: 0.17
Rob and I both looked over the patch separately and think it seems ok, and it passes the tests fine locally. I have applied it to trunk and we will to subject it to CI over the weekend to give it fuller workout before asking for inclusion in 0.16.
