TLDR
A verification and testing environment for Java, called Java PathFinder (JPF), which integrates model checking, program analysis and testing, and uses state compression to handle big states and partial order and symmetry reduction, slicing, abstraction, and runtime analysis techniques to reduce the state space.Abstract:
The majority of the work carried out in the formal methods community throughout the last three decades has (for good reasons) been devoted to special languages designed to make it easier to experiment with mechanized formal methods such as theorem provers and model checkers. In this paper, we give arguments for why we believe it is time for the formal methods community to shift some of its attention towards the analysis of programs written in modern programming languages. In keeping with this philosophy, we have developed a verification and testing environment for Java, called Java PathFinder (JPF), which integrates model checking, program analysis and testing. Part of this work has consisted of building a new Java Virtual Machine that interprets Java bytecode. JPF uses state compression to handle large states, and partial order reduction, slicing, abstraction and run-time analysis techniques to reduce the state space. JPF has been applied to a real-time avionics operating system developed at Honeywell, illustrating an intricate error, and to a model of a spacecraft controller, illustrating the combination of abstraction, run-time analysis and slicing with model checking.read more

No Java without caffeine: A tool for dynamic analysis of Java programs
TL;DR: Caffeine is a dynamic analysis tool that uses the Java platform debug architecture to generate a trace, and a Prolog engine to perform queries over the trace to help the maintainer in checking her conjecture about the behavior of a Java program.

Iterative delta debugging
TL;DR: Delta debugging minimizes the difference between two inputs, where one input is processed correctly while the other input causes a failure, using a series of test runs to determine the outcome of applied changes.

TL;DR: The results show that MuTMuT reduces the time for mutation testing, substantially over a straightforward mutant execution and up to 77% with the advanced technique over the basic technique.

SyncProf: detecting, localizing, and optimizing synchronization bottlenecks
Tingting Yu,Michael Pradel +1 more
TL;DR: The results show that SyncProf effectively localizes the root causes of these bottlenecks with higher precision than a state of the art lock contention profiler and that it suggests valuable strategies to avoid the bottlenekks.

Measuring the strength of information flows in programs
Wes Masri,Andy Podgurski +1 more
TL;DR: An empirical study is conducted in which the strength of information flows identified by DIFA are measured, using information theoretic and correlation-based methods, and it is indicated that flows due to data dependences alone are stronger, on average, than flowsDue to control dependence alone.

Statecharts: A visual formalism for complex systems
TL;DR: It is intended to demonstrate here that statecharts counter many of the objections raised against conventional state diagrams, and thus appear to render specification by diagrams an attractive and plausible approach.
