Hi Ramki,<br>
<br>
I added the hotspot-gc-dev mailing list to the CC. It should have
been<br>
there all the time.<br>

<div>How are you? Thanks for the heads-up; we really appreciate
it!

<div>I suspect the right thing to do in that case is to split
the CMS code off into its own subdirectory (which is to a
certain degree already the case), and to allow the
possibility of building it or not based on a build time
option or make target.
<div>That way the OpenJDK community can continue to use it
while Oracle can stop worrying about it.</div>

I think that would fit our needs. <br>

<div>May be we can discuss this within our respective teams
and then we can meet to discuss the details of how to make
this work?</div>

It would be nice to get a list of companies that would like to be
involved.<br>
Maybe an Openjdk project. Eventually with its own mailing list.<br>

<div>I haven't been monitoring the gc/openjdk aliases. If
this is being discussed there (and that would be the right
place so any othe teams interested in CMS can have a
voice), we'll make sure to join that discussion.</div>

As I said above, I meant to have the hotspot-gc-dev on the CC.<br>

I wanted to be sure you guys saw this JEP.<br>
<br>
Deprecate the CMS garbage collector (UseConcMarkSweepGC).<br>

I know you do development on CMS and wanted to know if<br>
had thoughts about the future of CMS.<br>
<br>
At some point Oracle is going to stop supporting CMS.<br>
The burden of testing and maintaining the CMS code doesn't<br>
make much sense given that we think G1 is the better<br>
collector. If we deprecate CMS in jdk9, support would be
dropped<br>
no earlier than jdk10.<br>
<br>
Have you guys talked about what you would like to do with
regard<br>
to continuing CMS development without Oracle's help?<br>
<br>
I've been told that if CMS exists in the Oracle binaries,
then<br>
customers will expect it to work. So not supporting CMS<br>
means it is not in the build.<span class="HOEnZb"><font
