[jboss-jira] [JBoss JIRA] Commented: (JBAS-3364) Support PROPAGATION_NESTED in JTA implementation

Yegor Yenikyeyev commented on JBAS-3364:
----------------------------------------

Thanks for the explanation, Mark! It looks pretty fair to me but what we were really trying to do (when i posted the issue) is just a nested JDBC transaction (which i believe JDBC 3.0 compliant and nested tx-aware) using the same datasource. 
The original issue was that I discovered a kind of deadlock of wrapping and nested transactions on an object in L2 cache (and this seems to be fixed in 1.4.x). Then i discovered this issue when i dug into details. As for me it looks like commit for nested tx (f2) is not being performed at all.
