Closed as program error.
Error description
When using the Unit of Work Manager, a Unit of Work may not throw errors back to the application when they occur during transaction completion - for example, if a resource drops out of the transaction during commit processing, the application may not be thrown an exception to indicate this event. This is contrary to the published API documentation, and may lead the application to believe a Unit of Work has been successful when it has in fact been rolled back. Note that this issue only occurs when using the UOWManager.runUnderUOW(int uowType, boolean join, ExtendedUOWAction uowAction, Class<?>[] rollbackOn, Class<?>[] dontRollbackOn) method. runUnderUOW methods with different signatures are not affected. Users may be experiencing this issue if they are seeing RollbackException or SystemException FFDCs originating in the runUnderUOW method, and which are not being reflected by corresponding failures in their application.

Problem conclusion
The code was erroneously ignoring some exceptions during transaction end processing. The code has been changed to wrap the exception in a UOWException and rethrow it. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.9.
