Instantiates and registers a MBean with the MBeanServer. The class loader to be used is identified by its object name. An object name is associated to the MBean. If the object name of the loader is not specified, the system ClassLoader will be used.If the MBean object name given is null, the MBean can automatically provide its own name by implementing the MBeanRegistration interface. The call returns a reference to the new instance and its object name.

className - The class name of the MBean to be instantiated.
name - The object name of the MBean. May be null.
params - An array containing the parameters of the constructor to be invoked.
signature - An array containing the signature of the constructor to be invoked.
loaderName - The object name of the class loader to be used.
Returns:
An ObjectInstance, containing the ObjectName and the Java class name of the newly instantiated MBean.
Throws:
ReflectionException - Wraps Wraps a ClassNotFoundException or a java.lang.Exception that occured trying to invoke the MBean's constructor.
InstanceAlreadyExistsException - The MBean is already under the control of the MBeanServer.
