(Seems that the issue is there since b93).
As soon as a connection is established, an output window is displayed containing an NPE stack dumped every sec or so.
Sometimes clicking on Tabs is not working.
I also observed that double clicking on an MBean attribute of type array doesn't enlarge the row to display the array value.

It occurs on Mac, I didn't try on other platform.
