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: 1GB2GBOS:
- 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
...
+ 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, 2GB min
- Minimum OS version: Mac OS X 10.7.3 Lion
- 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/ - 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

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. |
1. Get the code
| Code Block |
|---|
hg clone http://hg.openjdk.java.net/macosx-port/macosx-portjdk8/jdk8 cd macosx-portjdk8 chmod 755 get_source.sh ./get_source.sh |
2. Build
| Code Block | ||

* Steps for incremental building
3. Smoke Test
| Code Block |
|---|
build/macosx-universal/j2sdk-bundle/1.7.0.jdk/Contents/Homeimage/bin/java -version |
4. Install
| Code Block |
|---|
mkdir -p ~/Library/Java/JavaVirtualMachines cp -R build/macosx-universal/j2sdk-bundle/1jdk1.78.0.jdk ~jdk ~/Library/Java/JavaVirtualMachines |
5. Run
| Code Block |
|---|
export JAVA_HOME=`/usr/libexec/java_home home --version 1.7`7+` $JAVA_HOME/bin/java -version $JAVA_HOME/bin/java -jar /Developer/Extras/Java/JFC/SwingSet2/SwingSet2.jar |
If On Mac OS X 10.7 use the alternate location for the SwingSet2.jar if you have the Java Developer Package installed.:
| Code Block |
|---|
$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.
