Hi - is there a group of people working on OpenJDK 8 for OpenBSD?

One way to get an idea about the OpenBSD specific parts would be to
compare jdk7u/jdk7u to bsd-port/bsd-port as follows:
hg clone http://hg.openjdk.java.net/jdk7u/jdk7u
hg clone http://hg.openjdk.java.net/bsd-port/bsd-port
diff -uNpr -x build -x .hg\* -x \*.orig -x .hg -x .jcheck ../jdk7u .
This is shows the complete set of changes from Oracle's code base to our
code base for OpenJDK7. Greg and perhaps others have ported this over to
bsd-port/jdk8, so most of that work is done. Taking a quick peak at the
OpenBSD specific parts and I'm surprised how little is left. At one time
there was quite a bit of OpenBSD specific code needed. Hmm, actually I
just noticed some of our bsd-port changes make it into jdk7u already, so
this diff doesn't show all of the needed changes. I guess the next best
thing would be to do:
grep OpenBSD -IR .
This will get you pointed at the changes that were needed for OpenBSD in
OpenJDK 7. I think you will find that much of it was ported forward into
bsd-port/jdk8 when FreeBSD ported over to jdk8.
Some of the most critical code to get right lives in:
Problems in these areas generally leave you with a jdk that just doesn't
work. One good general test of the jdk is to build it, copy out the
resulting jdk image and use it to bootstrap the next build.

Thanks. Let me know when you've sent it in so I can be on the lookout
for your name showing up on the OCA list.
