Using jboss 4.0.5; a callback timer method on a stateless bean with transaction attribute REQUIRED_NEW does not seem to 'isolate' the transaction when called concurrently. A org.hibernate.StaleStateException occurs and the whole thing is rolled back.

@Timeout
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public void handleTimeout(Timer timer) {
// pseudo code:
// find obj (called on a different session bean with default settings)
// if found delete object
// The delete causes the stalestate when the entire batch is committed
}

According to the EJB3.0 specifiation the situation above should work, but it isn't unless I am doing things wrong. Any suggestions? Thanks in advance!
