RE: RequiredModelMBean bug?

Hi Ward,

you know how much I like ModelMBeans, and RMMB especially...
There is a clear overlapping between the management interface of the resource (managed by the RMMB) and the RMMB itself.
Am I allowed to call setModelMBeanInfo() via MBeanServer if that attribute is not exposed via MBeanAttributeInfo ?
I don't know the answer.

Frankly, I would avoid RMMB as much as possible.

For the rest, do whatever it seems more logical to you, I have no objections.

                              null, 
                              null,

                              null); 
    setModelMBeanInfo(info); 
  } 
  else

    ModelMBeanInfo info = (ModelMBeanInfo)persister.load(); 
    setModelMBeanInfo(info); 
  }
