Aries JDBC XA connection pool not working with Oracle database drivers

Issue

I've setup a XA JDBC connection pool for Oracle using 11g thin JDBC drivers as described here [1]
When trying to obtain a connection, I get the following exception in logs:

2014-10-23 22:49:49,780 | ERROR | _ALERTING_EVENT] | faultJmsMessageListenerContainer | 198 - org.apache.servicemix.bundles.spring-jms - 3.2.8.RELEASE_1 | Could not refresh JMS Connection for destination 'OMS.QN_ALERTING_EVENT' - retrying in 5000 ms. Cause: Error creating the db_connection; nested exception is java.lang.ClassCastException: org.tranql.connector.jdbc.ConnectionHandle cannot be cast to oracle.jdbc.internal.OracleConnection
