I've refactored the management code to use JSON for attributes, invocations and return values. This works well in most cases however we have a problem for return values which are TabularData. We can't directly return TabularData objects but we can return a Map whose values are Object[] which gives us basically the same thing. Problem is though this won't display nicely in jconsole.
