Description

If an XA prepare() raises an exception back to the client it results in the warning

WARN  FailoverTransport - Transport (tcp://127.0.0.1:61249) failed, reason:  java.io.IOException: 
Unexpected error occured: java.lang.ClassCastException: 
org.apache.activemq.command.ExceptionResponse cannot be cast to 
org.apache.activemq.command.IntegerResponse, attempting to automatically reconnect

which triggers a failover reconnect and a replay of the transaction which then causes

2013-12-20 13:38:12,581 [main] - WARN  TransactionContext - prepare of: 
XID:[86,globalId=00000001,branchId=00000001] failed with: javax.jms.JMSException: Cannot call prepare now.
