[jboss-jira] [JBoss JIRA] Commented: (JBAS-4481) Transaction timeouts leave garbage Status.ROLLEDBACK UserTransaction object bound to the thread

[Gavin King (JIRA)]

Gavin King commented on JBAS-4481:
----------------------------------

"what JTA allows and what JEE allows are sometimes different"

Which is why I filed this bug against JBoss AS, not against the TM.


"I've been telling you what we do and why we do it in general terms. You're obviously not interested in that, so I'll stop. "

I'm definitely not interested in that. I'm interested in fixing the bug in JBoss 4.2 


"Well you're wrong. You can't resume if there's already a transaction active on the thread, but you can resume the same transaction into multiple threads. "

Ooops, you're right, and this is an optional feature supported but not required by JTA. My bad. Nevertheless, its entirely academic, since the app is not allowed to get a TM in the first case.


"Not the timeout thread. But *something* obviously needs to."

Right, so can we quit the discussion and just fix the bug now?

> If a transaction timeout occurs, the UserTransaction object does not get cleaned up from the thread, even after the request ends and the thread returns to the pool. Future requests will not be able to begin() a transaction, since the STATUS_ROLLEDBACK UserTransaction throws this exception:
> Caused by: javax.transaction.NotSupportedException
> 	at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.begin(BaseTransaction.java:79)
> 	at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.begin(BaseTransactionManagerDelegate.java:77)
> 	at org.jboss.tm.usertx.client.ServerVMClientUserTransaction.begin(ServerVMClientUserTransaction.java:124)
> 	at org.jboss.seam.transaction.UTTransaction.begin(UTTransaction.java:29)
> This means that any transaction timeout that occurs will leave the application server in a permanently broken state and require a server restart. Hence 4.2.0.GA is currently unusable in production!
> This needs to be fixed in an immediate patch release.
