To help facilitate user testing, I've built and posted OpenJDK 7 binaries for Mac OS X 10.5 here:
openjdk7-darwin-i386-20080820.tar.bz2 (sig).
Help us find bugs -- give your code a try on OpenJDK 7, and send any issues along to the bsd-port-dev mailing list.
The long-term goal of the SoyLatte project was to ensure open, timely development of Java 7 for Mac OS X, with support for all recent versions of Mac OS X.
I'm pleased to announce that OpenJDK 7 is now runnable on both Mac OS X and the BSDs, as part of the OpenJDK BSD Port. The project represents the culmination of considerable work by Greg Lewis, Kurt Miller, Dalibor Topic, and myself.

OpenJDK uses Mercurial with the Forest extension. Before checking out the BSD sources, you will need to install and configure Mercurial. See the OpenJDK Developer's Guide for more information.
To check out the BSD-Port forest:
hg fclone http://hg.openjdk.java.net/bsd-port/bsd-port
As an alpha port to an in-development code base, some bugs are to be expected. Testers are most welcome.
Due to bugs in 10.4's compiler, building the sources currently requires a Mac OS X 10.5 machine.
Bootstrapping OpenJDK currently requires either SoyLatte 1.0.3, or a binary release of OpenJDK. The code base will not bootstrap against Apple's JVM.
Some portions of OpenJDK are still unavailable under an open-source license. To build OpenJDK, will also need Kurt Miller's binary plugs for the BSD port: jdk-7-icedtea-plugs-1.6.tar.gz. The binaries are derived from the IcedTea project.
To build the JDK in build/bsd-i586/j2sdk-image:
make \ ALT_BOOTDIR=/usr/local/soylatte-i386-1.0.3 ALT_BINARY_PLUGS_PATH=$HOME/jdk-7-icedtea-plugs \ ALT_FREETYPE_HEADERS_PATH=/usr/X11R6/include \ ALT_FREETYPE_LIB_PATH=/usr/X11R6/lib \ ALT_CUPS_HEADERS_PATH=/usr/include \ ANT_HOME=/usr/share/ant \ NO_DOCS=true \ HOTSPOT_BUILD_JOBS=1
Please make sure you're using the latest SoyLatte 1.0.3 release, or the build will fail.
The move to OpenJDK -- and Sun's re-licensing of the code under the GPL license -- opens the project to any interested contributer. Some exciting areas of exploration:
If you're interested in contributing, please join the bsd-port-dev mailing list.
With Sun's approval to merge the BSD Java patchset to OpenJDK squared away, Dalibor Topic has proposed project sponsorship for the BSD porting project.
If sponsorship is approved, the BSD Java Port -- which includes all the Soylatte changes -- will be able to officially join the OpenJDK project. Combined with the zero-assembler port, we could see OpenJDK 6/7 support in the near future for Mac x86 and PPC machines.
I'm very excited to see OpenJDK/BSD support progressing due to the hard work Dalibor Topic, Greg Lewis, and Kurt Miller.
