Distributed transaction fails with "ORA-01013: user requested cancel of current operation" in EAP 6

Issue

• Two servers are used in a distributed transaction
• The transaction coordinator timeout on both servers is set to a large value (e.g. 300 seconds / 5 minutes)
• An Oracle datasource pool is configured with set-tx-query-timeout set to true
• A transaction begun on server 1 propagates to server 2 where a database operation fails immediately with ORA-01013
