An read-only XA transaction that has a timeout never has the timer canceled when the transaction
is complete
------------------------------------------------------------------------------------------------------------

                 Key: DERBY-5562
                 URL: https://issues.apache.org/jira/browse/DERBY-5562
             Project: Derby
          Issue Type: Bug
          Components: Network Server
    Affects Versions: 10.8.2.2
         Environment: Solaris 10
Glassfish V2.1.1
            Reporter: Brett Bergquist


>From the EmbedConnection.java comment for "xa_prepare".


					// On a prepare call, xa allows an optimization that if the
					// transaction is read only, the RM can just go ahead and
					// commit it.  So if store returns this read only status -
					// meaning store has taken the liberty to commit already - we
					// needs to turn around and call internalCommit (without
					// committing the store again) to make sure the state is
					// consistent.  Since the transaction is read only, there is
					// probably not much that needs to be done.

When XATransactionController.XA_RDONLY is returned, no "commit" or "rollback" will be received.
 If a XA transaction timer was started (could be through the derby.jdbc.xaTransactionTimeout=xxx
for example), then these transactions will not have their timer canceled and will later attempt
to cancel the transaction and fail as the transaction no longer exists.
