    Hmm, you are right, the bracket I pointed to is unrelated. I guess the fix is in catchAny, which doesn't catch ThreadKilled. So not it's not rolling the transaction back in case of asynchronous exceptions. My point is that it probably should not rollback even on synchronous exception. BTW the issue is well know, see for example here
