JBoss integration with Oracle UCP datasource have occasional disconnections

Issue

• Oracle UCP driver occasionally gives connection closing exceptions causing failed requests to applications.
• There are two connection pools at work that contain different validation and reclaim policies, since data source had been set up at JBoss EAP to provide the JBoss connection pool and to pass the properties to application, where UCP had been programmed-in to use UCP connection pool. * AP > JBoss JCA > JBoss pool > UCP > UCP pool *
• A communication gap exists between the two pools (eg. UCP closes the connection but has no communication back to JBoss pool)
