Timothy Bish commented on AMQ-4950:
-----------------------------------

Looks like the offending code is here in TransactionContext 

{code}
            // Find out if the server wants to commit or rollback.
            IntegerResponse response = (IntegerResponse)syncSendPacketWithInterruptionHandling(info);
            if (XAResource.XA_RDONLY == response.getResult()) {
                // transaction stops now, may be syncs that need a callback
	        	synchronized(ENDED_XA_TRANSACTION_CONTEXTS) {
	                List<TransactionContext> l = ENDED_XA_TRANSACTION_CONTEXTS.remove(x);
	                if (l != null && !l.isEmpty()) {
	                    if (LOG.isDebugEnabled()) {
	                        LOG.debug("firing afterCommit callbacks on XA_RDONLY from prepare:
" + xid);
	                    }
	                    for (TransactionContext ctx : l) {
	                        ctx.afterCommit();
	                    }
	                }
	        	}
            }
{code}

We blindly cast to IntegerResponse before checking for error.
