This was originally sent to the OpenJDK Porters Development List, and reproduced here so I can shamelessly call for volunteers. If you've a desire to work on Mac OS X Java Integration, your help is always appreciated. Send me an e-mail, or join the OpenJDK porters group!

AWT Native Toolkit

I've spent a bit of time working on a native AWT toolkit. My initial tasks have been:

• Running the Cocoa event loop on the 'main' (first) thread
• Getting a window on the screen
• Drawing to the window

The first two items are done -- It's possible to display a basic AWT window (CPanelPeer, CWindowPeer), but not draw to it.

In pursuit of drawing, I've begun work on implementing a MacGraphicsDevice and a MacGraphicsEnvironment -- my current plan is to leverage the existing java2d OpenGL pipeline, if possible. I'm still getting my head around the best approach to this, especially in relation to resolution independence on Leopard.

If you'd like to check out the work, it's available via the development mercurial repository:

http://hg.bikemonkey.org/javasrc_1_6_jrl_darwin/

The code is currently located in:

j2se/src/solaris/classes/sun/awt/mac/
j2se/src/solaris/native/sun/awt/mac/

I will probably need to move the Mac-specific code out of the j2se/src/solaris directory. One of my goals is to retain support for both the X11 and the CG/Cocoa AWT toolkits.

The build only AWT, you can cd to j2se/make/sun/awt and run:

make ALT_BOOTDIR=/System/Library/Frameworks/JavaVM.framework/Home \
ALT_MOTIF_DIR=/opt/local SYS_CFLAGS="" LANG="C" JAVA_HOME="" CLASSPATH="" \
LD_LIBRARY_PATH="" MAKEFLAGS="" SKIP_COMPARE_IMAGES="YES" \
BUILD_DEPLOY="false" ALT_DEVTOOLS_PATH=/usr ALT_CUPS_HEADERS_PATH=/usr/include \
HOTSPOT_BUILD_JOBS=5 PARALLEL_BUILD_JOBS=5 \
ALT_HOTSPOT_CLIENT_PATH=/usr/local/soylatte16-i386-1.0/jre/lib/i386/client/ \
ALT_HOTSPOT_SERVER_PATH=/usr/local/soylatte16-i386-1.0/jre/lib/i386/server/

This will output a working JVM in j2se/build/bsd-i586. For the initial build, you make need to run make from top-level j2se/make directory.

Merge to BSD Repository

I've completed the merge of the Mac OS X port to the BSD Java project. With this work done, I've split Mac OS X development into two branches:

• Development - Integration with Mac OS X-specific technology (native AWT, etc.)
• Stable - A baseline Mac OS X port without additional native integration. Synchronized with the BSD repository.

General Release

After several weeks of using SoyLatte for my own development, and the testing of an exceptional group of early adopters, it's time to issue a 1.0 release. This release provides:

• A stable JVM, usable for real-world development
• The benefits of Java 6 performance enhancements
• X11 Swing (Nothing is perfect!)

Download Information

Changes since DP3

The only change in the 1.0 release is the acceptance of the -XstartOnFirstThread option. Nearly all outstanding changes have been merged upstream into the BSD Java project, and I have split development into two branches -- a stable branch, and an unstable branch. It's my intention (and I have begun work on) integrating Mac OS X-specific functionality within the unstable development branch.
