     * The sequence of events for tracking inter-MXBean references is
     * relatively complicated.  We use the magical preRegister2 method
     * which the MBeanServer knows about.  The steps during registration
     * are:
     * (1) Call user preRegister, if any.  If exception, abandon.
     * (2) Call preRegister2 and hence this register method.  If exception,
     * call postRegister(false) and abandon.
     * (3) Try to register the MBean.  If exception, call registerFailed()
     * which will call the unregister method.  (Also call postRegister(false).)
     * (4) If we get this far, we can call postRegister(true).
     *
     * When we are wrapped in an instance of javax.management.StandardMBean,
     * things are simpler.  That class calls this method from its preRegister,
     * and propagates any exception.  There is no user preRegister in this case.
     * If this method succeeds but registration subsequently fails,
     * StandardMBean calls unregister from its postRegister(false) method.
