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; }
