Moritz Barnickel enhanced static analysis capabilities in the soot-oss/SootUp repository by developing advanced call graph analysis features for multi-threaded Java applications. He modernized core algorithms, introduced incremental call graph initialization, and improved handling of implicit entry points such as Thread.run and Thread.start, addressing complex scenarios in bytecode analysis. Using Java and leveraging object-oriented design, Moritz refactored legacy APIs, stabilized static initializer processing, and expanded test coverage to ensure reliability across configurations. His work improved analysis accuracy, maintainability, and CI stability, demonstrating a deep understanding of software engineering principles and a methodical approach to evolving large-scale static analysis tooling.

Aug 1, 2025August 2025 highlights for soot-oss/SootUp: Delivered core enhancements to static analysis pipelines focusing on accuracy, reliability, and maintainability. Key features include modernization of the AbstractCallGraphAlgorithm with improved bound handling, constructor overloads, and pruning, plus Rapid Type Analysis (RTA) enhancements with a new pruning algorithm and explicit pre-instantiated class handling. API cleanup reduced legacy complexity. Comprehensive test updates across both features validated behavior across configurations and aligned with the current development branch. The work improves call graph accuracy and analysis performance, enabling faster triage, safer refactors, and more scalable maintenance.

Jul 1, 2025In July 2025, delivered a new Incremental Call Graph Initialization API for the soot-oss/SootUp repository, enabling initialization of the call graph with pre-instantiated classes to support incremental construction. This enhances flexibility for incremental analysis and reduces overhead when rebuilding graphs for large codebases. An accompanying unit test was added to validate that specified classes are correctly recognized and processed during initialization. Commit associated with the work: c3c6451472e133242f16babaae3abf7d17110b64 (issue 924 + test case).
