/**
* Allows the MBean to perform any operations it needs before being registered in the MBean
* server. If the name of the MBean is not specified, the MBean can provide a name for its
* registration. If any exception is raised, the MBean will not be registered in the MBean server.
*
* @param server The MBean server in which the MBean will be registered.
* @param name The object name of the MBean. This name is null if the name parameter to one of the
* createMBean or registerMBean methods in the MBeanServer interface is null. In that case,
* this method will try to guess its MBean name by examining its configuration data. If its
* configuration data is null (nothing was provided in the constructor) or doesn't contain a
* name, this method returns {@code null}, and registration will fail.
* <p>Otherwise, if {@code name} wasn't {@code null} or if a default name could be
* constructed, the name of the configuration will be set to the value of the ObjectName's
* {@code name=} key, and the configuration data will always be renamed to reflect this
* change.
* @return The name under which the MBean is to be registered.
* @throws Exception This exception will be caught by the MBean server and re-thrown as an
* MBeanRegistrationException.
