August 30 – September 1, 2006 Edited by: Ralf Gitzel, Markus Aleksy, Martin Schader, Chandra Krintz A Volume in the ACM International Conference Proceedings Series Message from the Chairs Dear conference participants, We are very pleased and proud to present you with the proceedings of the 4th International Conference on the Principles and Practices of Programming in Java (PPPJ 2006). After a short break in 2005, it is good to see that the conference has not only kept its impetus of 2004 but actually has attracted even more submissions and has received increased interest. This year’s call for papers resulted in 47 submissions. In our rigorous review process, every submitted paper was carefully examined by at least three program committee members. Ultimately, the committee accepted 17 full papers and 7 short papers, leading to an acceptance rate of 36% for full papers. We are happy to say that the papers selected are of high quality and cover a wide range of topics of interest to the Java community. Due to the support of three major interest groups (ACM SIGAPP, ACM SIGPLAN, and the GI Fachgruppe 2.1.4), we were able to recruit a wide spectrum of specialist reviewers. The program committee consisted of 36 members each with varying backgrounds, expertise, and research areas that covered the wide range of topics of interest to the PPPJ community. In a transparent and discussion-based process, only the best papers were chosen for the conference. Organizing a conference such as the PPPJ 2006 is of course a team effort. And while it is our names that grace the front cover as editors, we gladly admit that we had the help of many very professional people. Thus, it is only fitting and proper that we take this opportunity to thank them. In particular, we are indebted to the international program committee and the PPPJ steering committee for helping to ensure the success of PPPJ06 and future events in the PPPJ line. We also thank Thomas Preuss for providing us with the excellent ConfMaster submissions software that has taken a great administrative burden from our shoulders. We owe thanks to Priya Nagpurkar, our submission chair, who very professionally contributed to the submission and review process. ACM SIGPLAN and SIGAPP as well as the German GI Fachgruppe 2.1.4 deserve our gratitude for their support, especially regarding the recruitment of reviewers and publicity for the conference. Finally, we thank the authors of all submitted papers, who have allowed us to present you with such an interesting program. We hope that you find the 2006 PPPJ final program inspiring and that the conference provides you with the opportunity to interact, share ideas with, and learn from other Java researchers from around the world. We also encourage you to continue to participate in future PPPJ conferences, to increase its visibility, and to interest others in contributing to this growing community.
