Julius Stroffek commented on DERBY-2220:
----------------------------------------
> Is point 2 (Forbid the call to XAConnection.close when there is a global
> transaction
> associated with the corresponding resource) a necessary part of this bug fix,
> or would it be better to discuss/fix it under a separate issue?
Ok Knut, to make thinks simpler for discussion I have created a separate issue
for this - DERBY-2420. I will move the discussion there...
> abortCurrentTransaction() checks (e.errorCode != XAException.XA_RBOTHER &&
> e.errorCode != XAException.XA_RBROLLBACK).
> Would it make sense to test (errorCode < XA_RBBASE || errorCode > XA_RBEND)
> instead?
Yes, it would. Thanks, I have not noticed that fields in XAException.
> - there is a test for XAConnection.close() that is supposed to fail. What
> about adding a test case where it doesn't fail?
I think, this case is already covered by xaSimplePositive.sql and
xaSimpleNegative.sql and other XA tests.
And I completely agree with all your other comments. I'll prepare a patch for
those under the new issue.
> Uncommitted transactions executed throught XAResource will held locks after
> the application terminates (or crashes during the transaction).
