Unreported Transaction timeout on commit (Oracle)

Question

I'm expecting an Oracle error upon commit using "deferred constraints" and
          executing an INSERT that should result in a constraint violation. I am not
          seeing an error but the transaction hangs for 30seconds (JTA timeout
          setting) and then continues without an exception. The session bean client
          has no indication that the transaction has failed.
          I've tried implicit and explicit transations from the client and the session
          bean is marked as required.
          Weblogic: 8.1 sp1
          DB: Oracle 8.1.6
          Driver: Oracle Thin XA
          How is it possible that Oracle fails upon commit but the JDBC connection
          waits for a timeout, and ALSO how is it possible that I'm not seeing a
          transaction timeout exception?
          (i've changed the JTA timeout setting to verify that this is the timeout
          that is occuring and sure enough if i make it 20 seconds it returns after
          20, 60, etc...)

Settings in Domain_name-JTA and Services-JTA are essentially the same settings. At least this is what I see - my changes to Services-JTA are reflected in Domain_name-JTA.
