    INES researchers will be presenting a paper at the 13th workshop on Formal Techniques for Java-Like Programs. This workshop is part of ECOOP’2011 and is one of the main forums for discussing ideas about new techniques for the design, implementation, and evolution of Java programs that rely on a rigorous foundation. This year, FTfJP will be held in Lancaster, United Kingdom. INES will cover the expenses with registration at the workshop for one of the authors.

    Title: On the Interplay of Exception Handling and Design by Contract: An Aspect-Oriented Recovery Approach

    Authors: Henrique Rebêlo, Roberta Coelho, Ricardo Lima, Gary T. Leavens, Marieke Huisman, Alexandre Mota, Fernando Castor

    Abstract:

    Design by Contract (DbC) is a technique for developing and improving functional software correctness through definition of “contracts” between client classes and their suppliers. Such contracts are enforced during runtime and if any of them is violated a runtime error should occur. Runtime assertions checkers (RACs) are a well-known technique that enforces such contracts. Although they are largely used to implement the DbC technique in contemporary languages, like Java, studies have shown that characteristics of contemporary exception handling mechanisms can discard contract violations detected by RACs. As a result, a contract violation may not be reflected in a runtime error, breaking the supporting hypothesis of DbC. This paper presents an error recovery technique for RACs that tackles such limitations. This technique relies on aspect-oriented programming in order to extend the functionalities of existing RACs stopping contract violations from being discarded. We applied the recovery technique on top of five Java-based contemporary RACs (i.e., JML/jml, JML/a jml, JContractor, CEAP, and Jose). Preliminary results have shown that the proposed technique could actually prevent the contract violations from being discarded regardless of the characteristics of the exception handling code of the target application.

    The paper “A Design Rule Language for Aspect-Oriented Programming” was accepted for publication in the XIII Brazilian Symposium on Programming Languages - (SBLP 2009). The article is part of the project “Tool Support for Software Product Lines Development and Evolution” (Goal: Develop techniques, tools and domain-specific languages for modularization of the implementation of features in software product lines) and will be presented by the member Alberto Costa Neto of the project from 19 to 21 August 2009 in Gramado / RS.

    Aspect-Oriented Programming is known as a technique to modularize crosscutting concerns. However, buildings that are designed to support crosscutting modularity can break the modularity of the class. This can be mitigated through Design Rules between classes and aspects. We present a language that supports many of the Design Rules found in aspect-oriented systems, making it easier to express and check them automatically. We discuss how our language improves the crosscutting modularity without breaking the modularity of the class. Furthermore, we give some details about the semantics of the language expressed in Alloy
