Goals
- Pass all appropriate certification tests for Java SE 7
- Include a complete, native Cocoa-based UI Toolkit
- Provide excellent performance
- Integrate into main-line 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 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
- Mac OS X 10.7.3
- Xcode: 4.1 or later from the Mac App Store (free download)
- Mercurial: http://mercurial.berkwood.com/
- Jtreg: http://openjdk.java.net/jtreg/
| Note | ||

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. |
1. Get the code
| Code Block |
|---|
hg clone http://hg.openjdk.java.net/jdk7u/jdk7u-dev cd jdk7u-dev chmod 755 get_source.sh ./get_source.sh |
2. Build
| Code Block | ||
|---|---|---|
| ||
make ALLOW_DOWNLOADS=true ALT_BOOTDIR=`/usr/libexec/java_home -v 1.7+` HOTSPOT_BUILD_JOBS=`sysctl -n hw.ncpu` |
| Code Block | ||
|---|---|---|
| ||
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
| Code Block |
|---|
build/macosx-universal/j2sdk-image/bin/java -version |
4. Install
| Code Block |
|---|
mkdir -p ~/Library/Java/JavaVirtualMachines cp -R build/macosx-universal/j2sdk-bundle/1.7.0.jdk ~/Library/Java/JavaVirtualMachines |
5. Run
| Code Block |
|---|
export JAVA_HOME=`/usr/libexec/java_home --version 1.7` $JAVA_HOME/bin/java -version |
If you have the Java Developer Package installed:
| Code Block |
|---|
$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:
| 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.
