Artifact Evaluation Policy

The artifact has been evaluated as described in the ECOOP 2024 Call for Artifacts and the ACM Artifact Review and Badging Policy.

Abstract

This artifact supports the claim that different Java compilation environments can produce significantly different bytecode and that bytecode normalization applied via our tool jNorm heavily decreases the amount of compilation differences and helps boost the performance of subsequent code similarity analysis. Our artifact provides the source code of the tool jNorm and all scripts needed to reproduce the results we presented in our evaluation. Furthermore, it contains a study on the usage of different Java compilers and target levels within popular open-source projects, which showcases that the JDK compiler is by far the most relevant compiler in practice.
