Summary

Introduce an option to control use of the new notification mechanism introduced by JDK-8170299.

Problem

The fix for JDK-8170299 introduces a new NotificationThread. The fix moves all notification code from the ServiceThread to this new thread and makes this new thread visible to debugging facilities. To opt-out of using this new mechanism a new VM flag is required.

Solution

Add a new product option UseNotificationThread (default true) to allow users to select the new notification mechanism.
