I had to modify the activemq-admin script to adjust the SUNJMX
variable a bit to get it to work properly. Below is the full variable
after my modification:

SUNJMX="-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=1616
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false"

After adding the -Dcom.sun.management.jmxremote system property, the
activemq-admin script works as expected.

FWIW, the active-admin script's start function won't return. It just
runs ActiveMQ in place which is not what most people expect. So you
should probably use the activemq script or the wrapper executable to
startup ActiveMQ. Once it's started, you can use the activemq-admin
script to perform the other functions.
