Kristian Waagan commented on DERBY-2532:
----------------------------------------

I'm confused.

I thought the problem is that XAConnection.getXAResource() doesn't thrown an exception if the XAConnection is closed?
As far as I understand, it should be allowed to call XAConnection.close() several times, and doing this should not result in an exception.

So maybe adding a check to see if the connection has been closed in getXAResource would be a fix? This would match the behavior of the embedded driver.
