A Translator of Java Programs to TADDs

The model checking tools Uppaal and VerICS accept a description of a network of Timed Automata with Discrete Data (TADDs) as input. Thus, to verify a concurrent programwritten in Java by means of these tools, first a TADD model of the program must be build. Therefore, we have developed the J2TADD tool that translates a Java program to a network of TADDs; the paper presents this tool. The J2TADD tool works in two stages. The first one consists in translation of a Java code to an internal assembly language (IAL). Then, the resulting assembly code is translated to a network of TADDs. We exemplify the use of the translator by means of the following well-known concurrency examples written in Java: race condition problem, dining philosophers problem, single sleeping barber problem and readers and writers problem.

Towards Verification of Java Programs in VerICS

VerICS is a tool for the automated verification of timed automata and protocols written in both the Intermediate Language and the specification language Estelle. Recently, the tool has been extended to work with Timed Automata with Discrete Data and with multi-agent systems. This paper presents a prototype Timed Automata with Discrete Data model of Java programs. In addition, we show how to use the model together with the verification core of VerICS to validate the well-known alternating bit protocol written in Java. # Greedy Algorithm for Attribute Reduction
