Worked on modularizing the uber/NullAway library to enable compatibility with the Java Platform Module System, focusing on improving accessibility and integration for modular Java applications. The project involved reorganizing the codebase into a multi-module layout and introducing a modular annotations JAR, which reduces classpath complexity and supports safer adoption in modern Java toolchains. Using Java and modular programming techniques, the changes aligned the repository with JPMS best practices and laid the foundation for future module-wide enhancements. Documentation and rationale for the architectural update were included in the commit, closing a key issue and clarifying the intended use of the new modules.
