The state machine was not immeadiately for the service layer, but
will be used to enforce illegal transitions if we decide on a state
diagram.
The suggested change makes sense, but the other problem is the fact
that the deployment layer is out of the loop in this. I would like
to couple dependency and life cycle to delay the creation of the
service as an mbean, but have not really looked at how big a change
this is.

dependencies are not taken into account.

(operation.equals("create")) { // the current create() method } etc.

|
| This would be invoked from ServiceController.ServiceProxy when it is implemented
by the MBean.
|
| This would allow us to change the current
| ServiceMBeanSupport.create() to be:
| serviceController.create(serviceName);
| etc.
|
| Now clicking stop() in the console goes via the service controller making sure
dependencies are also stopped.
|
| This doesn't fix the problem for MBeans that do not extend ServiceMBeanSupport.
These would still do the old behaviour.
| Similar changes would be required to ServiceDynamicMBeanSupport and the XMBean
descriptor include.
