wrapXAResource can't be enabled.

Transaction diagnostics can be improved through the use of the information provided by XAResourceWrapper. However, this currently requires explicitly enabling. Further, it's not possible to enable it in the -ds.xml, only via JMX. This is pointless - it should be on by default.

When forcing it on, it blows up:

java.lang.NullPointerException
org.jboss.resource.connectionmanager.TxConnectionManager.createConnectionListener(TxConnectionManager.java:497)
org.jboss.resource.connectionmanager.InternalManagedConnectionPool.createConnectionEventListener(InternalManagedConnectionPool.java:647)

since the BaseWrapperManagedConnection implementation is incomplete:

public ManagedConnectionMetaData getMetaData() throws ResourceException

{ // TODO: implement this javax.resource.spi.ManagedConnection method return null; }
