ARTEMIS-5428 Hardening of the broker around PagingWrites / Shutdown
While the broker is being stopped, and if the system is paging, I
recently found a few issues that I am addressing here:
- When the server is stopped, the IDGenerator could be used after
the snapshot is generated, what could lead to data loss in case of a
regular shutdown while system under heavy load
- delayed Transaction could be completed after exceptions
(the markRollbackOnly or rollback should clear any pending state)
- The Acceptor notification is being called after the IDGenerator is
stopped (found this by accident after stopping the IDGEnerator).
