Hi,
This exception comes from an extra paranoia check
I added to TxCapsule in case somebody tries to
unregister a null XA resource.
Probably the real problem (if any) is in Minerva.
Looking at the Minerva source, it seems that the
XA resource has already been removed from the
HashMap, and it looks to me like this only can be
done after the resource was delisted from the
transaction.
Looks to me like a connectionClosed() event is
being posted twice, but I am not sure how this
could happen. After all, the connectionlistener
unregisters itself before delisting the resource.
Maybe the same listener is somehow being registered
twice with the same XAResourceImpl instance, but
that is unlikely as the listener only seems to be
registered in XAConnectionFactory.prepareObject().
The only way I can see this happening is if the
resource is obtained outside a transaction. In that
case the listener is registered, but the resource
is not added to the rms HashMap.
How does your callStoredProcedure() method look?
Best Regards,
Ole Husgaard.
