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/

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

...

6

...

$JAVA_HOME/bin/java -jar /Developer/Extras/Java/JFC/SwingSet2/SwingSet2.jar

...

.

...

Test

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