Resurrecting Ada´s Rendez-Vous in Java

Java is a programming language designed with concurrency in mind from its inception. However the synchronization mechanism provided is a restricted version of Hoare´s Monitors, being too low level for most applications. The authors propose a high level synchronization mechanism for Java, based on Ada´s Rendez-Vous, adapting the notation and semantics to Java. The result is a nice and readable notation to control concurrency, even cleaner than the Ada original version. The Rendez-Vous syntax adds only one statement to Java, and they developed a preprocessor to translate the new statement to pure Java, using a class library which supports messages. Their implementation is available for downloading over the Internet
