     * Multiple AttachAPIs will be tried in order of service priority.

     * as agent association happens immediately upon application start and cannot be undone or retried at a later time.
     * 
     * These services will only be used if the associated agent is not provided via java command line argument.
     * 
     * @Return the Class that represents VirtualMachine class and associated methods, or null to indicate 
     * this AttachAPIResolver cannot handle the request for this JVM.
