Goals
- Pass all appropriate certification tests for Java SE 7
- Include a complete, native Cocoa-based UI Toolkit
- Provide excellent performance
Minimum requirements to run
- An Intel Mac
- RAM: 1GB
- OS: Mac OS X 10.6.7 or later
- Java: "Java for Mac OS X 10.6 Update 4" or later
TL;DR
- Download an unofficial build
- Open /Applications/Utilities/Java Preferences.app
- Drag both "OpenJDK 7" entries to the top of the list
- Run "java -version" in Terminal.app
Prerequisites to build
- Hardware: Any 64-bit capable Intel Mac
- RAM: 4GB, 2GB min
- OS: Mac OS X 10.6, run Software Update to get to at least 10.6.7
- Xcode: 3.2.6 or later from http://developer.apple.com (Mac Dev Center section)
- Java: "Java for Mac OS X 10.6 Update 4" or later from http://connect.apple.com (Java section)
- Mercurial: http://mercurial.berkwood.com/
- Jtreg: http://openjdk.java.net/jtreg/
Xcode 4
If you install Xcode 4, you will have to re-install "Java for Mac OS X Update 4" or a later developer preview to correct headers in the JavaRuntimeSupport framework.
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`
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
Testing the Cocoa-based AWT
$JAVA_HOME/bin/java -jar /Developer/Extras/Java/JFC/SwingSet2/SwingSet2.jar
Iterative development of a particular module, AWT for example (avoid having to build whole JDK)
export JDK7_BASE=/Volumes/Data/src/JDK7/macosx-port export JDK7_BUILD=$JDK7_BASE/build export ALT_BOOTDIR=$JDK7_BUILD/macosx-universal/j2sdk-image/ export ALT_JDK_IMPORT_PATH=$JDK7_BUILD/macosx-universal/j2sdk-image/ export ALT_OUTPUTDIR=$JDK7_BUILD/macosx-universal cd $JDK7_BASE/jdk/make/sun/awt/ make
Settting bootclasspath, DYLD_LIBRARY_PATH and debugging with your changes:
compilation export _JAVA_OPTIONS=-Xbootclasspath/p:$JDK7_BUILD/macosx-universal/classes/ export DYLD_LIBRARY_PATH=$JDK7_BUILD/macosx-universal/lib/ $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.
