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+ 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 10.6, run Software Update to get to at least 10.6.57.3 Lion
- Xcode Command Line Tools
- Mercurial: Xcode: 3.2.5 or later from http://developermercurial.appleberkwood.com (Mac Dev Center section)Java: "Java for Mac /
- 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:
- Mercurial: http://mercurial.berkwood.com/
- Jtreg: http://openjdk.java.net/jtreg/
Setup
...
1. Get the code
| Code Block |
|---|
cd /tmp hg clone http://bitbucket.org/pmezard/hgforest-crew/ cp hgforest-crew/forest.py ~/.forest.py |
Add the following lines to your: ~/.hgrc
| Code Block |
|---|
[extensions]
hgext.forest=~/.forest.py
|
Source
| Code Block |
|---|
hg fclone http://hg.openjdk.java.net/macosx-port/macosx-port
|
Build
hg.openjdk.java.net/jdk8/jdk8
cd jdk8
chmod 755 get_source.sh
./get_source.sh
|
2. Build
| Code Block | ||
|---|---|---|
| ||
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`

* 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/1jdk1.7.0.jdk ~/Library/Java/JavaVirtualMachines |
| Panel |
The "1.7.8.0.jdk" bundle can be copied or symlinked to ~/Library/Java/JavaVirtualMachinesor /Library/Java/JavaVirtualMachines. Once installed, the build will be discovered by /Applications/Utilities/Java Preferences.app, and found using the /usr/libexec/java_home tool, when passing it "--version 1.7". By dragging the 1.7.0 version to the top of the Java Preferences lists, it will become the default JVM for command line use (since CommandLine is currently the only capability it supports).
|
5. Run
| Code Block |
|---|
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:
| Code Block |
|---|
$JAVA_HOME/bin/java -jar /Library/Java/Demos/JFC/SwingSet2/SwingSet2.jar
|
6. Test
The linux jtreg is just a shell script that runs fine on Mac OS X. It will run all the tests under $SRCDownload jtreg to run the tests in the /jdk/test directory.
| Code Block |
|---|
cd $SRC/jdk/
(path to jtreg)/linux/bin/jtreg .

If your version of Xcode is older than 3.2.5, the 32-bit build won't run, but the 64-bit build will.
