Where do JDK 9,10 fixes get pushed to?

Andrew Haley
Looks like nothing is going into jdk9 / hs / hotspot.  Everything now goes into
jdk9 / dev / hotspot.  I guess this is normal during rampdown?

But with JDK 10, jdk10 / hs / hotspot is live, and so is  jdk10 / jdk10 / hotspot.

How does this work?  Is there a two-way merge going on?

Thanks,

Andrew.

Right, jdk9/hs is closed as we are ramping down and the number of Hotspot changes in JDK 9 is fairly small at this point.

jdk10/jdk10 (a.k.a. 10/10) is the main JDK 10 forest. jdk10/hs (10/hs) is a child of 10/10. 10/hs is where JDK 10 Hotspot changes should be pushed. These changes will go through an extra layer of testing before being integrated to 10/10.

Currently changes are frequently pulled from 10/10 to 10/hs to keep 10/hs in sync, but so far we have not started to push changes from 10/hs to 10/10. Pushing 10/hs to 10/10 would complicate the forward ports currently being done on a weekly basis from JDK 9 so we are holding off with hs integrations until the frequency of changes in JDK 9 goes down.

Hth,
