[jbosscache-dev] Re: DummyTransaction and DumyTransactionManager

[Jonathan Halliday]

No, the status is determined before any of the 
afterCompletions run and does not change. An 
afterCompletions success/failure does not change the 
transaction outcome. They are in effect receiving 
notification of an earlier event and the notifications are 
independent, may happen in arbitrary order or even in 
parallel. Well, aside from the use of 
TransactionSynchronizationRegistry, but that's another story.
