DynamicMBean declares the management interface whereas Standard MBean
defines it by its XXXMBean interface. Dynamic MBeans implements the
DynamicMBean
interface.

For standard MBeans JMX looks for an interface using the convention
XXXMBean.
Therefore it can get confused when a DynamicMBean does the same. I would
guess
that it first look that it implements DynamicMBean and then check for
standard MBean
but seems that some people at Sun are not as bright as you expect.
