Moritz Barnickel enhanced static analysis capabilities in the soot-oss/SootUp repository by developing advanced call graph analysis features for multi-threaded Java code. He modernized core algorithms, improved handling of implicit entry points, and introduced incremental call graph initialization, enabling more accurate and flexible analysis. His work included refactoring control flow graph representations, stabilizing static initializer processing, and expanding test infrastructure for reliability. Using Java, shell scripting, and Markdown, Moritz focused on maintainable API design, code organization, and comprehensive documentation. These contributions improved analysis accuracy, reduced technical debt, and supported scalable development and onboarding for the SootUp static analysis platform.

Oct 1, 2025October 2025: Focused on codebase refactor and consistency improvements in the SootUp repository. Completed renaming of core CFG types from StmtGraph to ControlFlowGraph and MutableStmtGraph to MutableControlFlowGraph, aligning representations with interprocedural flow analysis concepts. The refactor improves readability, reduces ambiguity for contributors, and lays the groundwork for future CFG-driven analyses. While no customer-facing features were released this month, the changes enhance maintainability and future deliverability. Notable git activity includes a series of rename-related commits and targeted fixes to CFG creation logic to ensure stability during the transition.

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).
