This paper presents a clone-detection method/tool currently under development. This tool is useful as a code-clone search through the entire lifecycle of a software product; The tool searches code examples and analyzes of code clones in both preventive and postmortem ways[LRHK10]. The approach is based on a sequence equivalence on execution paths[Kam13] and extends the equivalence to include gaps, thus type-3[BKA+07] clone detection. Each of the detected clones is a sub-sequence of an execution path of a given program, in other words, a set of code fragments of multiple procedures (methods) which can be executed in a run of the program. The approach is relaxed in terms of adaptability to incomplete (not-yetfinished) code, but also makes use of concrete information such as types (including hierarchy) and dynamic dispatch when such information is available.
