Then maybe do as Steve suggested, either:
- introduce a new method to Synchronization (that would break existing 
synchronizations)
or
- introduce a new interface SynchronizationRollback which can be optionally 
implemented by the synchronization method
Then in JDBC transaction we could do:

if ((sync instanceof SynchronizationRollback) && ((SynchronizationRollback) 
sync).shouldRollback(exception) { // rollback }
