Hello,

I used Twiddle Standalone (https://github.com/swesource/twiddle-standalone) as twiddle feature is not available in Wildfly 8.2.0-Final.

When I executed the twiddle command for START, STOP, DESTROY lifecycle methods of MBeans, it worked fine and below are the commands used.

START - ./twiddle.sh -s service:jmx:http-remoting-jmx://localhost:9990 invoke test.mbeans:service=Importer start

STOP - ./twiddle.sh -s service:jmx:http-remoting-jmx://localhost:9990 invoke test.mbeans:service=Importer stop

DESTROY - ./twiddle.sh -s service:jmx:http-remoting-jmx://localhost:9990 invoke test.mbeans:service=Importer destroy

After executing DESTROY, I am trying to CREATE the MBean using twiddle but getting the below exception related to classloader.

CREATE - ./twiddle.sh -s service:jmx:http-remoting-jmx://localhost:9990 create com.it.test.jmx.Importer test.mbeans:service=Importer

There is an option to send class loader as one of the parameter in the command but I am not aware of the value to be sent. Has anyone faced this issue ? Please help.
