      Description

      I am unable to connect from the log4j2 Client GUI, regardless of whether running it as a JConsole Plug-in, or running it as a standalone application.

      Below are details of what I've used in my attempts:

      My application

      • ran from Netbeans, with these VM arguments:
        -Djava.security.policy=~/Downloads/policy -Djavax.management.builder.initial= -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9010 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false
      • I've tried various ports: 9010, 1099, 33445 etc
      • Content of my policy file (I've allowed everything):
        grant {
        permission java.security.AllPermission;
        };

      Running the Client GUI as a JConsole Plug-in

      • command I used to execute:
        jconsole -pluginpath /Downloads/Software/Development/Java/log4j/2.0/rc1/apache-log4j-2.0-rc1-bin/log4j-core-2.0-rc1.jar:/Downloads/Software/Development/Java/log4j/2.0/rc1/apache-log4j-2.0-rc1-bin/log4j-jmx-gui-2.0-rc1.jar
      • The JConsole starts without issue, but I don't see the Log4j2 tab as per the manual (http://logging.apache.org/log4j/2.x/manual/jmx.html)

      Running the Client GUI as a Stand-alone Application

      • command I used to execute (I'm running this from the directory where the JARs are:
        java -cp log4j-core-2.0-rc1.jar:log4j-jmx-gui-2.0-rc1.jar org.apache.logging.log4j.jmx.gui.ClientGUI localhost:9010
      • however, i getting a java.lang.NoClassDefFoundError:
