"Connection is not associated with a managed connection" and "result set is closed" errors with Spring + Hibernate in EAP 6

Issue

• Using nested queries (e.g. Hibernate query during a JdbcTemplate query OR nested Hibernate queries)
• Using org.springframework.orm.jpa.JpaTransactionManager for the transaction manager
• Outer queries fail with exceptions such as the following:

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

java.sql.SQLException: The result set is closed.
