Jaca - a software fault injection tool

Abstract

This work presents Jaca, a fault injection tool that aims to validate Java applications. Jaca injects high-level software faults by affecting attributes and methods of an object's public interface. Jaca is source-code independent: instrumentation needed for injection and monitoring purposes are introduced at bytecode level during load-time. Jaca's usefulness is shown in a case study used to validate a third-parties component. The case study consists of an OODBMS named Ozone as a component and a performance benchmark, Wisconsin OO7, which uses the OODBMS’ stored objects.
