Open JDK

What you will find here

Today this project contains two significant components of the JDK:

• The HotSpot Virtual Machine
• The Java programming-language compiler (javac),
  with complete NetBeans project metadata

The remainder of the open-source JDK will be available in the first half of 2007. At that time this project will host the source code for the complete JDK except for a few components that Sun does not have the right to publish in source form under the GPL; pre-built binaries will be provided for those components.

You will also find the jtreg unit-test harness here, for use in running the compiler's unit tests. For now this tool is available only in binary form, but eventually it too will be open-sourced.

OpenJDK-6 source code available

The source code for the JDK 6 project is now available here. To learn more about this new effort please see Joe Darcy's blog; to get involved please join us on the jdk6-dev list.

Draft Developers' Guide available

Iris Clark has posted the first draft of the OpenJDK Developers' Guide. Please send comments to guide-discuss(at)openjdk.java.net
