Monitor a JMS Topic's MessageCounters attribute using twiddle

Issue

• How can I monitor a JMS Topic's MessageCounters attribute using twiddle? The following command should work but fails:

./twiddle.sh -s localhost:1099 -u admin -p admin get "jboss.messaging:service=ServerPeer" MessageCounters

• Errors received:

ERROR [Twiddle] Exec failed
