The RV series of workshops brings together researchers from academia and - dustry that are interested in runtime veri?cation. The goal of the RV workshops is to study the ability to apply lightweight formal veri?cation during the exe- tion of programs. This approach complements the o?ine use of formal methods, which often use large resources. Runtime veri?cation methods and tools include the instrumentation of code with pieces of software that can help to test and monitor it online and detect, and sometimes prevent, potential faults. RV 2009 was held during June 26 28 in Grenoble, adjacent to CAV 2009. The program included 11 accepted papers. Two invited talks were given by AmirPnueli,on CompositionalApproachtoMonitoringLinearTemporalLogic Properties and Sriram Rajamani on Veri?cation, Testing and Statistics. The program also included three tutorials. We would like to thank the members of the Program Committee and ad- tional referees for the reviewing and participation in the discussions.
