All I can say is that I don't know anyone using the foreground collector, I don't know of anyone using the flags needed to turn on the foreground collector and I don't recall seeing any evidence of the foreground collector in any of the logs that I've looked at.

The review request is titled "JDK-8027132: Print deprecation warning message for the flags controlling the CMS foreground collector" and it would be good if any discussion can be handled in that email thread.

This is just to communicate that the foreground collector has been deprecated. Hopefully we will follow this up with a change to actually remove the support for the foreground collector for one of the future major releases.
