Communicates with an MBean providing a JMX interface to a HotSpotGraalRuntime instance. The MBean will be dynamically created when a JMX client attaches or some other event causes the platform MBean server to be started.

Polls this registration to see if the MBean is registered in a MBean server.

Params:
  • sync – synchronize with other threads that may be processing this registration. This is
           useful when the caller knows the server is active (e.g., it has a reference to
           server) and expects this poll to therefore return a non-null value.
Returns:an ObjectName that can be used to access the MBean or null if the MBean has not been registered with an MBean server (e.g., no JMX client has attached to the VM)
