Heads up: Deprecating the CMS foreground mode

[Bengt Rutisson]

Hi all,

Just a heads up for anyone using the CMS foreground collector.

I just sent out a review request to this list that proposes a change to 
print warning messages for the flags that enable the CMS foreground 
collector. 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.

We don't know of anyone using the foreground collector, so I thought I'd 
send out an extra email out to draw some attention to the review request 
if there is anybody using it.

Just to be clear. The change proposed now only prints warning messages 
for some flags. Everything will keep working as before. 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.

Thanks,
Bengt
