The changes to hotspot may need to take a slightly different ride into jdk8, so
I'd suggest doing that work separately
with the hotspot team.
For everything else, if someone could prepare webrevs of the BSD changes for
each repository involved, and send
them to the build-...@openjdk.java.net alias, we can get reviews started and
get the changes integrated.
I have a feeling that as the changes get reviewed we might have some cleanup
ideas.
Keep in mind that we cannot and will not just drag over all the changesets in
the existing BSD/MAC repositories,
we will need to create fresh, probably large, changesets that identify
themselves as BSD or MAC porting
changes. We can create multiple CRs and break it up into separate pieces if
necessary.
If you need CRs filed, let me know. So the detailed history and the changesets
in the BSD/MAC repositories will
stay with those repositories, just so people understand.
Formally getting BSD builds to happen on a regular basis may be an issue, but
first step (in my opinion) is to
get the source code and makefile logic merged in, making sure the existing
platform builds are not impacted.
If someone has references to BSD iso images I can at least get started on
creating my own VirtualBox setup.
---
I have a major concern here with the build changes involved colliding with our
build infrastructure changes
and the jigsaw/modularity changes coming into jdk8.
Right now, jdk8 is basically jdk7 plus a little change, so doing this now may
be best, but it needs to happen
quickly, if we wait too long, the merge could be very painful.
