"Connection is not associated with a managed connection" when Connection is reused in JBoss EAP

Issue

• Application code is caching Connection and Statement / PreparedStatement references in local fields/instance variables.

• When the references are re-used some time after their original initialization, exceptions like the below are encountered:

  java.sql.SQLException: Connection is not associated with a managed connection.org.jboss.jca.adapters.jdbc.jdk8.WrappedConnectionJDK8@174b8c5
  

  java.sql.SQLException: Connection is not associated with a managed connection.org.jboss.jca.adapters.jdbc.jdk7.WrappedConnectionJDK7@174b8c5
  

  java.sql.SQLException: Connection is not associated with a managed connection.org.jboss.jca.adapters.jdbc.jdk6.WrappedConnectionJDK6@174b8c5
  

  java.sql.SQLException: Connection is not associated with a managed connection.org.jboss.resource.adapter.jdbc.WrappedConnection@19ce161
  

• The connection package/class varies with EAP version.
