* and key properties are specified, all objects are to be selected (and filtered if a query is
* specified). It returns the set of <CODE>ObjectInstance</CODE> objects (containing the <CODE>
* ObjectName</CODE> and the Java Class name) for the selected MBeans.
*
* @param name The object name pattern identifying the MBeans to be retrieved. If null or or no
* domain and key properties are specified, all the MBeans registered will be retrieved.
* @param query The query expression to be applied for selecting MBeans. If null no query
* expression will be applied for selecting MBeans.
* @return A set containing the <CODE>ObjectInstance</CODE> objects for the selected MBeans. If no
* MBean satisfies the query an empty list is returned.
