I have the same issue:

"Monitoring is not started for the selected JVM" with "Start Monitoring" 
getting stuck and disappering some time later, not actually starting the 
monitoring. Does not work with either running or debugging an application or 
trying to monitor the eclipse jvm.
The .log does not say anything related to JVM except a message when I quit 
Eclipse while "Start moitoring" still runs, telling me that plugins should 
terminate their processes on shutdown.

Any updates on this issue?

"Same problem. I double click on a vm, nothing happens except the properties 
tab opens with nothing inside."

I get the same on JDK 7, Windows 7, Eclipse Luna.
