Manual JMX Server setup error: RHQ 4.3.0

Aurelio Calegari Newbie

I'm a big fan of RHQ and have been using RHQ 3.0 for a long while. I currently just started migrating to RHQ 4.3.0 and I was testing it. I'm unable to register a JMX Server manually as I used to. Here's my settings:

 

Agent running on a windows box, server on a Fedora.

 

On the windows platform (below its27940), in the inventory, I tried to add a new JMX Service:

Which connects well with JVisualVM:

But when I hit Finish, I got an error message in the server side and the following stack trace in the agent side:
