Attempt to disablePlugin using RHQ CLI fails. I tried to do the following:

*************************************************
$ ./rhq-cli.sh -u rhqadmin -p rhqadmin -s test.usersys.redhat.com -t 7080
RHQ Enterprise Remote CLI 4.12.0.JON330GA Update 09

rhqadmin.redhat.com:7080$ var plugins = PluginManager.findPluginsByCriteria(pluginCriteria); 
rhqadmin.redhat.com:7080$ var myPlugin = plugins.get(0);
rhqadmin.redhat.com:7080$ var pluginID = myPlugin.getId()
rhqadmin.redhat.com:7080$ var allPluginIDs = []
rhqadmin.redhat.com:7080$ allPluginIDs.push(pluginID);
1.0
rhqadmin.redhat.com:7080$ pretty.print(allPluginIDs);
one row

rhqadmin.redhat.com:7080$ PluginManager.disablePlugins(allPluginIDs);
org.jboss.remoting.CannotConnectException: Can not connect http client invoker after 1 attempt(s)

and the following was logged in the server.log file:
