Goals

Prerequisites

Xcode 4

If you install Xcode 4, you will have to re-install "Java for Mac OS X Update 4" or a later developer preview to correct headers in the JavaRuntimeSupport framework.

Source

hg clone http://hg.openjdk.java.net/macosx-port/macosx-port
cd macosx-port
chmod 755 get_source.sh
./get_source.sh

Build

make ALLOW_DOWNLOADS=true SA_APPLE_BOOT_JAVA=true ALWAYS_PASS_TEST_GAMMA=true ALT_BOOTDIR=`/usr/libexec/java_home -v 1.6` HOTSPOT_BUILD_JOBS=`sysctl -n hw.ncpu`

Smoke Test

$ build/macosx-universal/j2sdk-bundle/1.7.0.jdk/Contents/Home/bin/java -version

Install

mkdir -p ~/Library/Java/JavaVirtualMachines
cp -R build/macosx-universal/j2sdk-bundle/1.7.0.jdk ~/Library/Java/JavaVirtualMachines

The "1.7.0.jdk" bundle can be copied or symlinked to ~/Library/Java/JavaVirtualMachines or /Library/Java/JavaVirtualMachines.

Once installed, the build will be discovered by /Applications/Utilities/Java Preferences.app, and found using the /usr/libexec/java_home tool, when passing it "--version 1.7".

By dragging the 1.7.0 version to the top of the Java Preferences lists, it will become the default JVM for command line use (since CommandLine is currently the only capability it supports).

Run

export JAVA_HOME=`/usr/libexec/java_home --version 1.7`
$JAVA_HOME/bin/java -version

Testing the Cocoa-based AWT

export AWT_TOOLKIT=CToolkit
$JAVA_HOME/bin/java -jar /Developer/Extras/Java/JFC/SwingSet2/SwingSet2.jar

Test

Download jtreg to run the tests in the /jdk/test directory.
