75       This method creates a new MBeanServer implementation object. When creating a new
76       MBeanServer the MBeanServerFactory first calls newMBeanServerDelegate() in
77       order to obtain a new MBeanServerDelegate for the new MBeanServer. Then it
78       calls newMBeanServer(defaultDomain,outer,delegate) passing the delegate that
79       should be used by the MBeanServer implementation.
80       Note that the passed delegate might not be directly the MBeanServerDelegate that
81       was returned by this implementation. It could be, for instance, a new object
82       wrapping the previously returned delegate.
83
84       The outer parameter is a pointer to the MBeanServer that should be passed
85       to the MBeanRegistration interface when registering MBeans inside the
86       MBeanServer. If outer is null, then the MBeanServer implementation must
87       use its own this reference when invoking the MBeanRegistration interface.
88
89       This makes it possible for a MBeanServer implementation to wrap another MBeanServer
90       implementation, in order to implement, e.g, security checks, or to prevent
91       access to the actual MBeanServer implementation by returning a pointer to a wrapping object.
92
93         Parameters:
94         defaultDomain - Default domain of the new MBeanServer.
95         outer - A pointer to the MBeanServer object that must be passed to the MBeans when invoking their MBeanRegistration interface.
96         delegate - A pointer to the MBeanServerDelegate associated with the new MBeanServer. The new MBeanServer must register this MBean in its MBean repository.
97         Returns:
98         A new private implementation of an MBeanServer.
