I'm certainly not in a position to pass judgment one way or the other,but sJava seemed (based on a very quick, perhaps uncomprehending scan) somewhat cluttered in comparison with JCSP. And the idea of using method calls INSTEAD of channels seems to accentuate - at least syntactically - the "orthogonality" of OOP and threading.
