Brett Bergquist commented on DERBY-5562:
----------------------------------------
It appears the timer was implemented in
https://issues.apache.org/jira/browse/DERBY-2508 which has a fix at 10.3.1.4
> An read-only XA transaction that has a timeout never has the timer canceled
> when the transaction is complete
> ------------------------------------------------------------------------------------------------------------

> 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.
