Goals

• Pass all appropriate certification tests for Java SE 7
• Include a complete, native Cocoa-based UI Toolkit
  • DONE.
• Provide excellent performance
• Integrate into main-line OpenJDK 8 
  • DONE. OS X is now 'just another platform' in OpenJDK 8

Minimum requirements to run

• An Intel Mac
• RAM: 2GB
• Mac OS X 10.7.3

Note that only Mac OS X 10.7.3 and higher will be an Oracle-supported platform. It should continue to run on 10.6.8+ Java for Mac OS X 10.6 Update 6 but that is not guaranteed. As of 1-Jan-2012 there are no plans to introduce 10.7-only APIs into the codebase.

Prerequisites to build

• Hardware: Any 64-bit capable Intel Mac
  • RAM: 4GB
• Minimum OS version: Mac OS X 10.7.3 Lion
• Xcode : 4.1 or later from the Mac App Store (free download)Command Line Tools

• Mercurial: http://mercurial.berkwood.com/

• X11
  • On OS X 10.8 Mountain Lion: XQuartz
  • On OS X 10.7 Lion: Run /Applications/Utilities/X11.app to install as an additional download

JTReg is not required to build but useful for running regression tests

• Jtreg: http://openjdk.java.net/jtreg/

...

As of Xcode version 4.3 you have to manually install the Command Line Tools. This package is no more included by default. (Start Xcode, open preferences, open tab Downloads and there install the missing component.)

1. Get the code

hg clone http://hg.openjdk.java.net/jdk7ujdk8/jdk7u-devjdk8
cd jdk7u-devjdk8
chmod 755 get_source.sh
./get_source.sh

2. Build

CPATH="/usr/X11/include" LANG=C make ALLOW_DOWNLOADS=true ALT_BOOTDIR=`/usr/libexec/java_home -v 1.7+` HOTSPOT_BUILD_JOBS=`sysctl -n hw.ncpu`

CPATH="/usr/X11/include" LANG=C 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`

* Steps for incremental building

3. Smoke Test

build/macosx-universal/j2sdk-image/bin/java -version

4. Install

mkdir -p ~/Library/Java/JavaVirtualMachines
cp -R build/macosx-universal/j2sdk-bundle/1jdk1.78.0.jdk ~jdk ~/Library/Java/JavaVirtualMachines

5. Run

export JAVA_HOME=`/usr/libexec/java_home home --version 1.7`7+`
$JAVA_HOME/bin/java -version

If you have the Java Developer Package installed:

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

On Mac OS X 10.6 use the alternate location for the SwingSet2.jar:

$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.
