has given me a platform to share my programming topics to entire world. Surprisingly this is the 6th year. Realizing that I am not consistent in doing blog. Before a couple of days I could retrieve my logins after 1-2 years. In this 6th year anniversary, I like to resume...
Building past snapshots of a software project has shown to be of interest both for researchers and practitioners. However, little attention has been devote
At the same time, we noticed that a small number of projects have eliminated many uses of these methods, employing the CountDownLatch class, part of the java.util.concurrent library, instead. This number is not large enough for statistical analysis. Nevertheless, it indicates that mechanisms ...
Methods structure The essential choice for modelling the behaviour of programs is to get a finite, parameterized representation that take into account the pa- rameters of recursive methods, and the representation of objects in the store. We give the rational for these two points, before describing...
A customization of these techniques is needed to embed a set of “change type” rules that are relevant for security weaknesses (e.g., replace mutableMapOf with ConcurrentHashMap if the class extends Thread). Another common weakness related to the improper control of resources is CWE-668: Exp...

Over the years, Design by Contract (DbC) has evolved as a powerful concept for program documentation, testing, and verification. Contracts formally specify assertions on (mostly) object-oriented programs: pre- and postconditions of methods, class invariants, allowed call orders, etc. Missing in th...
What types of execution traces can NOD4J record, and how does it handle incomplete traces? How does the parameter k influence the size of recorded execution traces? What are the main features of the NOD4J tool for debugging Java programs?
datasets for our study in Section5.1. We also analyzed the test execution time of the test cases in the Vul4J dataset. The results, which was reported in Section5.3, aided us determine the proper execution time settings for running APR tools to repair the vulnerable programs in the Vul4J ...
(2012). In practice, cross-project validation for OSS case consists in a 6-fold cross validation, in which folds are neither stratified nor randomly taken, but correspond exactly to the different systems: In the open source case, we train the classifiers on five systems and we try to ...
