  abstract= "The use of formal methods in the development of concurrent
     systems considerably reduces the complexity of specifying
     their behaviour and verifying properties that are inherent
     to them. Development, however, targets the generation of
     executable programs; hence, translating the final
     specification into a practical programming language
     becomes imperative. This translation is usually rather
     problematic due to the high probability of introducing
     errors in manual translations: the mapping from some of the
     original concepts in the formal concurrency model into a
     corresponding construct in the programming language
     is non-trivial. In recent years, there is a growing effort
     in providing automatic translation from formal
     specifications into programming languages. One of these
     efforts, JCircus, translates specifications written in
     Circus (a combination of Z and CSP) into Java programs
     that use JCSP, a library that implements most of the CSP
     constructs. The subtle differences between JCSP and Circus
     implementation of concurrency, however, imposed restrictions
     to the translation strategy and, consequently, to JCircus.
     In this paper, we extend JCircus by providing: (1) a new
     optimised translation strategy to multi-way synchronisation;
     (2) the translation of complex communications, and; (3) the
     translation of CSP sharing parallel and interleaving. A
     performance analysis of the resulting code is also in the
     context of this paper and provides important insights into
     the practical use of our results."
