[wildfly-dev] a way to obtain local ModelController within javaagent?

[John Mazzitelli]

OK, here's another one where I need some secret magical sauce - hoping someone knows of a technique I can use.

Suppose I have a javaagent installed in a WildFly server (using the standard -javaagent VM argument).

The javaagent would like to talk to the WildFly Server it is co-located with. Since it is in the same VM, the javaagent wants to avoid it looking like a remote call. 

But I know of no way to obtain a local ModelController instance to build a client short of injecting some service or subsystem into WildFly itself (something I would like to avoid).

If the javaagent were instead a subsystem extension, it could do something like this:

   InjectedValue<ModelController> mcValue = new InjectedValue<>();
   ...
   ((ServiceBuilder) bldr).addDependency(Services.JBOSS_SERVER_CONTROLLER, ModelController.class, mcValue);
   ...
   WHAT_I_WANT = mcValue.getValue().createClient(...)

But obviously, that's no good for something running outside of the WildFly container (albeit in the same JVM).

Any hope at all? I was thinking some trickery on the order of what ByteMan does in order to figure out a way to obtain a local ModelController? But that's a last ditch effort :) Hoping there is something that uses a little less witchcraft.
