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 10.7.0 or 10.6.8
  • Java: Java for Mac OS X Developer Preview (11M3511+10M3511)

Prerequisites to build

• Hardware: Any 64-bit capable Intel Mac
  • RAM: 4GB, 2GB min
• OS: Mac OS X 10.7
  • Xcode: 4.1 or later from the Mac App Store (free download)
  • Java: "Java for Mac OS X 10.7" ("java -version" to trigger install)
• OS: Mac OS X 10.6, run Software Update to get to at least 10.6.8
  • Xcode: 3.2.6 or later from http://connect.apple.com (Developer Tools section)
  • Java: "Java for Mac OS X 10.6 Update 5" or later from Software Update or 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

On Mac OS X 10.7 use the alternate location for the SwingSet2.jar if you have the Java Developer Package installed.

$JAVA_HOME/bin/java -jar /Library/Java/Demos/JFC/SwingSet2/SwingSet2.jar 

6. Test

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

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 /Applications/Utilities/Terminal.app
