Issue

With Fuse 6.2, occasionally it is not possible to connect a JMX client (e.g., jconsole) to a running Fuse process. If the problem is present when Fuse starts, it will not resolve itself -- a restart is necessary.

if the JMX client shows exceptions, it will typically show an exception like this:
