Mac OS X Port

Goals

• Pass all appropriate certification tests for Java SE 7
• Include a complete, native Cocoa-based UI Toolkit
• Provide excellent performance
• Integrate into main-line OpenJDK 8

Minimum requirements to run

• An Intel Mac
• RAM: 1GB
• OS: Mac OS X 10.6.7 or later
• Java: "Java for Mac OS X 10.6 Update 4" or later

TL;DR

1. Download an unofficial build
2. Open /Applications/Utilities/Java Preferences.app
3. Drag both "OpenJDK 7" entries to the top of the list
4. Run "java -version" in Terminal.app

Prerequisites to build

• Hardware: Any 64-bit capable Intel Mac
  • RAM: 4GB, 2GB min
• OS: Mac OS X 10.6, run Software Update to get to at least 10.6.7
• Xcode: 3.2.6 or later from http://developer.apple.com (Mac Dev Center section)
• Java: "Java for Mac OS X 10.6 Update 4" or later from http://connect.apple.com (Java section)
• Mercurial: http://mercurial.berkwood.com/
• Jtreg: http://openjdk.java.net/jtreg/

1. Get the code

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

2. 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`

• Incremental Building

3. Smoke Test

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

4. Install

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

5. Run

export JAVA_HOME=`/usr/libexec/java_home --version 1.7`
$JAVA_HOME/bin/java -version
$JAVA_HOME/bin/java -jar /Developer/Extras/Java/JFC/SwingSet2/SwingSet2.jar

6. Test

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