Project Lambda
JSR 335 (Lambda Expressions for the JavaTM Programming Language) aims to support programming in a multicore environment by adding closures and related features to the Java language.
JSR 335 is part of JSR 337 (Java SE 8). The Early Draft Review #1 of JSR 335 has been published.
The goal of OpenJDK Project Lambda is to host a prototype implementation of JSR 335 suitable for inclusion in JDK 8, the Reference Implementation of Java SE 8. The prototype implementation is discussed on the lambda-dev mailing list.
The prototype compiler is being implemented in OpenJDK.
- Source code is available at http://hg.openjdk.java.net/lambda/lambda.
- Binary snapshots of the lambda-enabled JDK prototype are available at http://jdk8.java.net/lambda.
This Project is sponsored by the Compiler Group.
