Let's say we have two MBean classes A and B.

The AMBean exposes a method "delete" than when invoked calls unregisterMBean
on the 1 and 2 instances of the BMBean and then calls registerMBean on a new
instance 3 of the BMBean.

First of all, the agent registers in the MBeanServer three MBean instances
named as follows:

test:type=A
test:type=B,name=1
test:type=B,name=2

We connect to the agent with JConsole and see that the MBean tree displays:

test
  |
  |---> A
  |
  |---> B
    |
    |---> 1
    |
    |---> 2

then we call the "delete" method on the AMBean singleton.

After the invocation the MBeanServer contents look like:

test:type=A
test:type=B,name=3

But in JConsole the only MBean we can see is:

test
  |
  |---> A

The MBean tree hasn't been correctly refreshed and the instance 3 of the
BMBean is missing.
