SlicedBread is a library that makes it simpler to program multithreaded applications in Java. It does so by doing away with "classic" multithreaded staples - that is, shared state using thread-safe objects - in favor of a set of single-threaded processes that send and receive immutable messages. In a sense it is inspired by Erlang's messaging system. In another, the over 400 rich pages of "Java concurrency in practice" show how hard it is to write and debug a good-mannered multithreaded application in Java.


This release includes the first version of the documentation, which should be enough to get you started with the library. It adds thread pools (multiple threads reading from the same mailbox) and checks thread safety under JMM (JSR-133).
