It seems like I have to create the NetworkConnector first or it messes up the
ManagementContext.
But if I do create the NetworkConnector first, it *seems* like it creates a
ManagementContext on it's own and it uses the default port (1099). But I
already have another broker on the machine using 1099 for the jmx port.
I'm kind of confused at how I get these two objects constructed in the right
way, since they both *seem* to depend on each other.
Or maybe it's not the port, maybe it's the broker name?
