Oct 1, 2025In 2025-10, delivered two focal changes in JetBrainsRuntime that improve reliability and usability. Windows Test Timeout Stabilization reduced test flakiness on Windows by introducing an explicit timeout value and updating test metadata with the associated bug ID to prevent tests from running indefinitely. Javadoc Members Sorting Feature added lexicographical sorting of Javadoc member details with a new toggle button and JavaScript to switch between source order and alphabetical order, enhancing documentation navigability.

Apr 1, 2025April 2025: Maintained and improved stability in JetBrainsRuntime by delivering a critical reliability fix to JavadocTokenizer. The change prevents potential infinite loops and edge-case resize issues during documentation parsing, strengthening parser resilience under heavy or malformed input. Key updates include overflow handling for the 'grow' variable, throwing IndexOutOfBoundsException when growth overflows to non-positive, and correcting map resizing logic when grow equals map.length. These changes reduce hangs/crashes in downstream tooling and CI, improving developer experience and confidence in the parser. The work is traceable to commit f66b9ba7bc1f426c430c5a99842685008c5a9dda (8346785: Potential infinite loop in JavadocTokenizer.ensures).
