Michael Musgrove commented on JBTM-2356:
----------------------------------------

Gytis tracked it down.

The bug is in the afterCompletion call where the coordinator does cleanup -  the (rest-at) coordinator maintains an in memory map of active transactions (and a one time read of the recovering transactions from disk at boot time). In this case it should be checking the transaction status before deciding to remove its in-memory copy of the transaction uid.

So when a participant asks for the status the coordinator has no knowledge of it. We didn't spot this in our tests because we only test crash recovery on a single server and in this case on restart the coordinator repopulates its view of recovering transactions.

Gytis has written a 2 server arquillian test to catch these cases in the future.

> Start two serves A and B with the coordinator running on A and a participant on server B. Crash server B just before commit. When server B comes back up the coordinator fails to recover the transaction and returns 404 when asked about the transaction.
