Core-java

A common practice for rapid prototyping of an object-oriented program analysis is to define a lightweight fragment of Java, that is sufficiently small to facilitate a rigorous analysis of key properties. Such a lightweight fragment lacks important Java features, thus the experimental evaluation on real-world code is not easy. The solution is either to extend the prototype to the whole Java or to rewrite the real-world code in the lightweight language. We propose an intermediate solution through Core-Java, an expression-oriented core calculus of Java and a comprehensive set of translation rules from Java to Core-Java. The translation can be guided by the specific requirements of each program analysis. We have built an implementation of our framework and have used it for two different analyses on Java programs.
