Retrolambda is a backport of Java 8's lambda expressions to Java 7, 6 and 5

Retrolambda lets you run Java 8 code with lambda expressions, method references and try-with-resources statements on Java 7, 6 or 5. It does this by transforming your Java 8 compiled bytecode so that it can run on an older Java runtime. After the transformation they are just a bunch of normal .class files, without any additional runtime dependencies.

The GitHub project can be found here: https://github.com/orfjackal/retrolambda
