MQ-JMSRA pooled connection validation broken: ManagedConnectionFactory does not implement ValidatingManagedConnectionFactory

[svendiedrichsen]

The class com.sun.messaging.jms.ra.ManagedConnectionFactory does not implement the interface javax.resource.spi.ValidatingManagedConnectionFactory. This prevents Application-Servers like i.e. Glassfish/Payara 4/5 to validate pooled JMS connections and has a variety of negative effects in case of broken connections.
