Regular sync-ups from the upstream?

I built the lambda tree just last night from MacOSX

I'd like to echo this.

I'm trying to write a patch to java.util.regex.Pattern, which implements methods for use with lambda expressions, to make using regexps easy in Java 8.

Unfortunately, I have a couple of problems:

1) The lambdas repo doesn't currently support Mac.

2) The JDK 8 repo (which is what we've cloned to github for the Adopt OpenJDK project) doesn't support the current implementation of lambdas
- it's a couple of versions behind.

If we could get the build changes into lambda, so it will build on Mac, I would be a happy man.
