This volume presents the reports from the workshops held in conjunction with the European Conference on Object-Oriented Programming (ECOOP 2008), taking place in its 22nd edition at Coral Beach in Paphos, Cyprus, July 7-11 2008. As is customary, the workshops introduced the conference, taking place on the first two days (July 7 and July 8 2008) prior to the main technical track. The workshops were first chosen through a rigorous process with stringent selection criteria, carried out by the members of the Workshop Selection Committee. This volume collects reports from the resulting high-quality workshops. The topics covered span areas related to object-oriented programming and technology, such as programming languages, aspects, parallel computing, formal techniques,
software engineering, tools, and applications. By summarizing the outcome of these workshops, this volume provides readers with a comprehensive set of pointers into current trends and issues of intense investigation and debate in the field of object-oriented technology. Following the tradition, the individual workshop reports summarize the workshop goals, before providing an overview of the presentations and sometimes also a summary of the issues and findings of debates fueled by the presentations. Some reports may also include a list of participants or contributed position papers. Several of the reports also contain a list of references to relevant publications and websites, including the workshop home page which usually offers the contributed position papers for download and may present further material.
