[jira] [Commented] (DBCP-383) NPE during XA commit (possibly doing
startup recovery)

Sebb commented on DBCP-383:
---------------------------
Looks like the NPE is caused by current Xid == null.
The current Xid is saved by start() and set to null by commit(), rollback() and forget(), so it looks like an invalid sequence of calls has been used.
However, the code should not throw an NPE.
It would be more helpful if it threw an IllegalStateException (or similar).

Martin Lichtin commented on DBCP-383:
-------------------------------------
It occured while running the test code from https://github.com/muellerc/camel-in-transaction
I have a slight problem re-running the test, as it almost always completely locks up my machine :(
After reboot, my guess is that Atomikos TM needs to recover some in-doubt transactions and then I saw above NPE.
