Other XAResource errors

Further to JBAS-3336 (resource manager error during enlist should close the connection).

There are other xa resource failures that need to be catered for.
e.g. a failure to delist probably means a problem with the connection.

Also, this could be dealt with at the rar level? e.g. the jdbc XAManagedConnection

public void end(Xid xid, int flags) throws XAException
{
+ try
+

{ xaResource.end(xid, flags); + }

+ catch (XAException e)
+

{ + broadcastConnectionError(e); + throw e; + }
