  • 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. Mac OS X is now 'just another platform' in OpenJDK 8

...

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.

If you install Xcode after installing the Apple provided Java for Mac OS X, you will have to re-install the same Java for Mac OS X or a later developer preview to correct headers in the JavaRuntimeSupport framework. This issue is expected to be resolved in a future release of Xcode.

As of Xcode version 4.3 you have to manually install the command line compilers and tools. Start Xcode, open Preferences, choose the Downloads tab, and then install "Command Line Tools".

1. Get the code

For JDK 7u

Code Block
hg clone http://hg.openjdk.java.net/jdk7u/jdk7u-dev
cd jdk7u-dev
chmod 755 get_source.sh
./get_source.sh

For JDK 8

Code Block
hg clone http://hg.openjdk.java.net/jdk8/jdk8
cd jdk8
chmod 755 get_source.sh
./get_source.sh

2. Build

...

Code Block
$ export LANG=C        # bash, ksh, etc.
% setenv LANG C        # csh and friends
Code Block
titleJava 7 or higher installed
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`
Code Block
titleUsing Apple's Java 6
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`

If you are building on Mountain Lion you must also define the path to the X11 includes:

Code Block
export CPATH="/usr/X11/include"

* Steps for incremental building

...

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

...

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

...

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

...

6

...

.

...

Code Block
$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.

  • Join the web-discuss@openjdk.java.net mailing list
  • Send an e-mail to the web-discuss@openjdk.java.net mailing list:
    • Request editor rights to the "OpenJDK Mac OS X Port" wiki
    • Include your Oracle SSO Username

TL;DR

...

  1. Open it
  2. Drag both "OpenJDK 7" entries to the top of the list
