Here is one of the stack trace that is thrown because the object is
in-commisionable state.
Here is what is happening in this part of the code.
- JMX Management handler (a component) is trying to register "Myclass" as
MBean with the MBean server.
- But before that, it checks whether the object is in commissionable state
and then this exception is thrown :(
java.lang.IllegalStateException: Cannot respond to resolve request as the
appliance appliance:/tutorial/Myclass is in a non-commissioned state.
