- 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: 1GB
- OS: Mac OS X 10.6.7 or later
- Java: "Java for Mac OS X 10.6 Update 4" or later
TL;DR

- 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
If you install Xcode (3.2.6 or 4) after installing "Java for Mac OS X Update 5", you will have to re-install "Java for Mac OS X Update 5" 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
