%X The Java * thread model provides support for multithreading
within the language and runtime system of Java. The Java
synchronization and scheduling strategy is poorly specified
and turns out to be of unsatisfactory real\-time
performance. The idea of Java is to let the underlying
operating system specify the synchronization and scheduling
principles. This may possibly result in different behavior
on different operating systems whereas Sun claims Java to be
system independent – "write once, run
everywhere". In this paper we present a comprehensive
specification for a new thread model for the Java
platform.The theory of CSP fully specifies the behavior of
synchronization and scheduling of threads at a higher level
of abstraction, which is based on processes, compositions
and synchronization primitives. The CSP concept is well
thought\-out and has been proven to be successful for
realizing concurrent software for real\-time and embedded
systems. The Communicating Threads for Java (CTJ) packages
that is presented in the paper provides a reliable
CSP/thread model for Java. The CTJ software is available
