<div>I've actually seen quite a few cases where people grep'd
globals.hpp, found the flag CMSFullGCsBeforeCompaction but not
knowing what it really is, and suffer from old gen
fragmentation problems when they set the flag to a value
greater than zero. It's more like a trap than a tool in these
cases. I'll be glad when this flag is gone ;-)</div>

Good point. Thanks!<br>

Thank you very much for this heads up. 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.<br>
<br>
So, unlike iCMS, I'm not about to add any resistance to the
decision to deprecate.<br>
<br>
Regards,<br>
Kirk<br>

proposes a change to print warning messages for 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.<br>

to draw some attention to the review request if there is
anybody using it.<br>

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.<br>
