NestedTopLevel transactions do not rollback state on exception -------------------------------------------------------------- Key: JBTM-2888 URL: https://issues.jboss.org/browse/JBTM-2888 Project: JBoss Transaction Manager Issue Type: Bug Components: STM Affects Versions: 5.5.24.Final Reporter: Michael Musgrove Assignee: Mark Little Attachments: NestedTopLevel2UnitTest.java The attached file is a reproducer. Drop it into the STM tests directory and run to see the failure. It creates two transactional objects A and B. B is further annotated with @NestedTopLevel. The test: - starts a transaction A; - calls a write method on A; - then calls a write method on B which throws an exception; - aborts or commits A (either outcome produces the error) Since the container starts a top-level transaction for the call to the method on B I would expect it to abort it if the B method throws an exception. What I find is that it will always call commit. This behaviour limits the usefulness of @NestedTopLevel when such methods are called inside an existing transaction since there is no mechanism for rolling back changes.
