Java™ Platform, Standard Edition 8 Early Access with Lambda Support

This page provides an Early Access of OpenJDK with Lambda (JSR 335) support. The Lambda project aims to support programming in a multicore environment by adding closures and related features to the Java language

For documentations and other details, please see the Lambda project page.

Please note:
The Lambda project has used source files that are not yet available in JDK8; therefore, these early access builds are created using the latest OpenJDK 7 source repository. This project will merge into OpenJDK 8 when the source files are available.

These bundles are meant to allow developers to try the Lambda features without making their own compilations. If you are looking for the latest JDK 8 builds, please download from here.
