I spent some more time working on the GC interface prototype and wanted
to share it with you:

http://cr.openjdk.java.net/~rkennke/gc-interface/webrev.02/
<http://cr.openjdk.java.net/%7Erkennke/gc-interface/webrev.02/>

Notable changes:

- It's now based on JDK10 (specifically,
http://hg.openjdk.java.net/jdk10/hs/hotspot changeset 12853:d276073fda85)
- I focused on better CMS isolation:
  - Most CMS specific stuff from GenCollectedHeap now resides in
specific subclass CMSHeap
  - Same for CardTableModRefBSForCTRS -> CMSBarrierSet
  - Factored everything related to always_do_update_barrier_set into CMS
subclasses

The JEP is still in 'submitted' state. Would be good to have it moved to
'candidate' at least, so that it gets a number?

https://bugs.openjdk.java.net/browse/JDK-8163329

Does anybody know a good place where I could put a whole forest to
develop this in?

As always, any feedback is welcome.

Best regards,
Roman
