visualVM Profiler error during calibration / startup

843798Dec 17 2009 — edited Jan 13 2010
I'm running visualVM 1.2.1 against jdk1.6.0_06, on Windows Vista Ultimate, SP2.
The Profiler does not appear to be working.

After startup / calibration, if I go to Help>About, and press on the Logfile button, I see these errors:

*** Profiler warning (Thu Dec 17 10:03:07 PST 2009): timed out while trying to connect to the target JVM.
*** Profiler error (Thu Dec 17 10:03:07 PST 2009): connection with server not open

I've read old postings about the NetBeans Profiler requiring certain ports, so I turned off the Windows Firewall,
and restarted visualVM. But the same error occurs.

What is going on? How can I get the visualVM Profiler to work?

Thanks.
