[JBoss-dev] AbstractKernelController behavior inconsistent

[Anil Saldhana]

Can I set an attribute on a JMX service that has been created but failed
to start (ServiceContext state is FAILED)?

Sorry.  I can make ServiceProxy transient myself.  I thought it was in
the mc code.

I will make the fix and check the updated testcase.

I can check in the updated test case once the ServiceProxy is made
transient. Can you make the fix?

No, the old one wasn't either, since it holds a link to the
MBeanServer (via the ServiceController) 
not an MBeanServerConnection (remote version).

The ServiceContext should be, so the ServiceProxy
inside it should be transient. i.e. not part of the
serialized form. 

But this looks like a bug that has been there forever.

How can it be an attribute, it takes a parameter?

I don't understand this? You cannot transistion from
unregistered to create. Once it is unregistered it doesn't exist.

Provide a complete example so we don't have to guess what you
talking about.
