Brian Egge reported in JBCLUSTER-83:

Running twiddle against the HAJNDI port will sometimes fail, and sometimes work. It does not matter if you query the server which has the component, or the failover server. Both produce the same result. Using the standard JDNI port always works, if you query the correct server. Using the HAJNDI fails ~50% of the time:

The JNDI port always works:
C:\JBossAdvancedJ2EE\labs\jboss-4.x\bin>twiddle --server=jnp://localhost:1199 get jboss.mq.destination:name=A,service=Queue" ReceiversCount QueueName
ReceiversCount=0
QueueName=A
C:\JBossAdvancedJ2EE\labs\jboss-4.x\bin>twiddle --server=jnp://localhost:1199 get "jboss.mq.destination:name=A,service=Queue" ReceiversCount QueueName
ReceiversCount=0
QueueName=A

• In these examples, clust2 is running using the bind config port-01, which adds 100 to the ports. The bug is the same when on a single machine or multiple. The above examples are the same when using 1099/1100.
