PQ60432: NO EXCEPTION THROW WHEN A DB2 ERROR OCCURS

APAR status
Closed as program error.

Error description
Problem :  The customer has DB2 XA enironment with one
local and one remote application database.  He shuts
down the remote application database, and the transaction
fails.  Before applying 
pq55352 (and subsequently pq55402),
an error was returned to the servlet.  Until DB2 apar
JR16724 was applied, the biggest problem was that at
pq48877 the customer received an exception, but the DB2
layer never recovered the XA transaction.
.
With the DB2 apar and PQ48877 the customer application
recovers.  But if they apply pq55402 they still see the
behavior where with the remote database down, the servlet
just hangs, and no exception is every thrown.

****************************************************************
Possible hangs when processing StaleConnectionExceptions.
Connections become unusable and do not recover. This
is similar to PQ55402 but for a different case - JTA
Enabled or XAConnection.
Problem conclusion
The code path for JTA was fixed so that it doesn't hang
when a stale connection occurs.
Temporary fix
Customer has the Fix and it works.
