    unable to connect to other process

    sascha4j

      Java Mission Control is a very important tool for me. i use it very often. unfortunately it  doesn't work any more on my developer machine and i didn't know what changed.  i am not able to connect to any other process any more. i got the message "JRockit is no longer supported" of course the jvm options -XX:+UnlockCommercialFeatures -XX:+FlightRecorder are set.  i tried different versions jdk 1.7.55 and jdk 1.8.60 but all the same.

       

      i use  a windows 7 machine  with 16 GB RAM.

       

      any idea what the problem is?

       

      JMC could  do a flight recording on its own.  but all other processes i got no chance.

          What happens if you try to run jcmd against those processes?

            For example jcmd 5084 VM.version

              then i got

               

              Java HotSpot(TM) 64-Bit Server VM version 24.55-b03

              JDK 7.0_55

                And if you do it for the JMC you are running?

                  i tried to do a flightrecording using jcmd JFR.start JFR.dump and JFR.stop

                   

                  it worked

                   

                  finally i am happy there is one solution.

                   

                  but it would still be nice to do it over the jmc ui.

                    for the jmc i am runinnig it works also.  if you look at the screenshot above. there is no "JRockit" for the JVM running mission control.

                      I am trying to figure out why it believes you are running JRockits since you're evidently running HotSpots.

                       

                      1. From within JMC, go to Help | About Oracle Java Mission Control. Tell me the full version number (something like Oracle® Java Mission Control 5.5.0 (M5.5.0-108, 165303))
                      2. If you are not running the latest JMC, please download the latest JDK 7 or JDK 8.
                      3. Follow the instructions here Mission Control Troubleshooting Tip – Logging | Marcus Hirt, to enable logging. Let me know what you get on your log when starting JMC.

                        the version Java Mission Control 5.5.0 (M5.5.0-108, 165303))

                          This is quite weird. Can you e-mail me at marcus.hirt at oracle.com? We'll set up a Skype call with screen sharing so that I can check out a few things. Optimally I'd like to hook up with JDWP to your JMC and check what the heck is going on.

                           

                          Until then, see if this FAQ helps:
