I ran jconsole, selected MBeans -> com.sun.management -> DiagnosticCommand -> Operations, and it shows the list of DCMDs (what we normally see as jcmds). I clicked on one and it has a `dcmd.permissionName` field with the permission in it. Is this an example of using JMX where you feel showing the permission is the right thing to do.
