I changed the title. We won't be exposing these over the other interfaces. This isn't really related to RBAC.

> It's not possible to call "non-published" operations (those that are not visible in the resource tree, e.g. {{describe}}) via JMX, while it's entirely possible to call them via CLI (e.g. {{/subsystem=security:describe}}) and other management interfaces.
> The problem lies in the fact that {{ModelControllerMBeanHelper.invoke}} method checks {{if (!accessControl.isExecutableOperation(operationName))}} and the {{isExecutableOperation}} method assumes that the operation will be visible in the resource tree. In fact, there is a comment stating _should not happen_, but now we know that it indeed _can_ happen.
> What's more, it gives a misleading error message. The {{isExecutableOperation}} returns {{false}} for unknown operations, which results in {{Not authorized to invoke operation}} message. Which is wrong in two different ways simultaneously: 1. the problem isn't authorization, but the fact that the operation can't be found; 2. the user (e.g. in the {{SuperUser}} role) _is_ authorized.
> I'm considering this low priority, because 1. JMX is likely to be very rarely used to access the management interface, 2. hiding information isn't nearly as important as leaking them, 3. non-published operations aren't nearly as important as the published ones. It's worth a JIRA nevertheless.
