Subject [jira] Commented: (OPENJPA-343) Do not call setRollbackOnly on inactive Transactions
Date Fri, 31 Aug 2007 01:16:30 GMT


Craig Russell commented on OPENJPA-343:

I agree that 1) not calling setRollbackOnly during afterCompletion is correct.

But when 2) an unexpected exception occurs during afterCompletion, like a NullPointerException,
it seems that we should log the exception. Even though it's during afterCompletion, we shouldn't
just swallow it. Of course, fixing 1) means that 2) can't be reliably reproduced. 

I'm not clear on what 3) means. 

> I plan to resolve issue (1) by checking for a valid transaction status before calling
setRollbackOnly. If the transaction is not in a suitable state, I will log a trace message
indicating that the setRollbackOnly can not be called, but processing will continue. 

I guess the issue is whether this is a trace scenario or a more serious problem that should
be reported back. We are still in commit as far as the application is concerned and it's not
obvious to me that this is a successful transaction. I'd think we should cause the outer level
transaction to fail with a SystemException because the application handling is not consistent
(the cache, for example, might be in an inconsistent state). If the application thinks everything
is aok, then I think we have a problem.

 While we (OpenJPA) were attempting to clean up after that exception, we attempted to call
setRollbackOnly on the current transaction.  But, since we were in the process of completing
the current transaction, it is invalid to be calling setRollbackOnly and we ended up getting
an IllegalStateException from the WebSphere Transaction Manager.  Due this second exception,
we ended up losing track of the original exception and this became a difficult problem to

lost the first exception in the first place and ensure that doesn't happen again.
