Worked on the JetBrainsRuntime repository to enhance the reliability of Java HttpClient authentication by enforcing the default retry limit. Addressed a bug where authentication attempts could exceed expectations, ensuring the client now adheres to a maximum of three retries as documented. Implemented regression tests across multiple HTTP versions and security configurations to validate the new behavior and prevent future regressions. Updated project documentation to clarify that the total number of authentication attempts equals the retry limit plus one. Utilized Java, HTTP Client, and testing frameworks, demonstrating a methodical approach to improving system properties and maintaining clear, accurate documentation.
