Mark Little commented on JBAS-4481:
-----------------------------------
"FYI, there may be an issue"
There is an issue in this situation if your application thread was calling rollback on the
timed-out transaction during cleanup. commit should have been fine, i.e., the application
thread would have been disassociated from the transaction correctly if commit was called,
but not rollback. Jonathan is working on producing a new version now.
Transaction timeouts leave garbage Status.ROLLEDBACK UserTransaction
object bound to the thread

Key: JBAS-4481
URL:
http://jira.jboss.com/jira/browse/JBAS-4481
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Transaction Manager
Affects Versions: JBossAS-4.2.0.GA
Reporter: Gavin King
Assigned To: Jonathan Halliday
Priority: Blocker
Fix For: JBossAS-4.2.1.CR1
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.
