Scala Native is the a new Scala compiler under development. This compiler will permit Scala users to compile directly Scala code to binary and use many functionalities of the C language such as memory allocation and most of the standard libraries. Since this compiler's target isn't Java Bytecode, the java libraries can't be used as is like for standard Scala, thus part of the work of Scala Native team is to write a Scala implementation for the Java libraries. This project aims to implement java.util.concurrent.* library for the Scala Native compiler.
