The RV sequence of workshops brings jointly researchers from academia and who're drawn to runtime verification. The objective of the RV workshops is to check the power to use light-weight formal verification through the execution of courses. This procedure enhances the offline use of formal tools which regularly use huge assets. Runtime verification tools and instruments contain the instrumentation of code with items of software program which may aid to check and display screen it on-line and observe, and infrequently hinder, capability faults.

RV 2009 was once hung on June 26-28 in Grenoble, France, adjoining to CAV 2009. this system integrated eleven accredited papers. invited talkswere given by way of Amir Pnueli on "Compositional method of tracking Linear Temporal good judgment homes" and Sriram Rajamani on "Verification, trying out and Statistics". this system additionally integrated 3 turorials.

Example text

In particular, for satisfying memory restrictions, the KVM abstains from the application of JIT compilation; instead, all programs are exclusively executed by an interpreter. For the development of a functional type-separated virtual machine, the KVM was extended by an additional classloader and a further interpreter, that perform the loading and execution of type-separated programs, respectively. In addition, to guarantee the correctness of loaded programs, a type-separated bytecode verifier, which is called implicitly from the classloader, was added to the runtime system.

Java Bytecode (in %) occurred during method invocations. e. a call of a re-implemented method must be dispatched to its defining class. This property has to be checked every time a virtual method is invoked and exhibits a further performance penalty. Since the first performance measurements were not satisfying, some optimizations were performed on the multi-stack implementation. e. an exclusive untyped parameter stack was added to speed-up method invocations. g. a better internal representation of used stacks and register planes, etc.

Code annotation for safe and efficient dynamic object resolution. , Zimmermann, W. ) Proceedings of the 2nd International Workshop on Compiler Optimization Meets Compiler Verification (COCV 2003), Warsaw, Poland, April 2003, pp. 18–32 (2003) 20. ca/soot/ 21. html 22. html 23. fr Abstract. The underlying property, its definition and representation play a major role when monitoring a system. Having a suitable and convenient framework to express properties is thus a concern for runtime analysis. It is desirable to delineate in this framework the spaces of properties for which runtime verification approaches can be applied to.
