In Fuse IDE then the JMX explorer may not appear to work, if you try to expand local processes, and nothing is shown.
The problem could be that you may have upgraded the JDK, or misconfigured the JDK settings in the Fuse IDE settings.
For example I upgraded from _18 to _31 and had the JDK settings changed/upgraded in various part of my windows box.
But Fuse IDE JMX explorer did not work for me, until I found this settings where I changed the path, and now it works again.
I think end users may hit this problem and we should add a FAQ.
