Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses compatibility issues encountered in Java 17+ environments where accessing the simple name of certain non-public inner classes triggers an IllegalAccessError. By centralizing class name retrieval through a new robust utility method, the changes ensure that the codebase remains resilient to these reflection-related restrictions while maintaining existing functionality.

Highlights

  • Robust Class Name Resolution: Introduced a new utility method ReflectHelpers.getSimpleName(Class) to safely retrieve class names, providing a fallback mechanism when Class.getSimpleName() throws exceptions like IllegalAccessError on newer Java versions.
  • Compatibility Fixes: Updated multiple locations in DisplayData, DoFnSignatures, and ReflectHelpers to use the new safe getSimpleName utility, ensuring compatibility with Java 17+ environments where non-public inner class access can be restricted.
New Features

Code Review

This pull request introduces a helper method ReflectHelpers.getSimpleName(Class<?>) to safely retrieve the simple name of a class, preventing potential exceptions (such as IllegalAccessError on Java 17+ for non-public inner classes) by falling back to parsing the class name. Direct calls to Class.getSimpleName() are replaced with this helper across several files. Feedback on the changes highlights that the fallback logic does not correctly handle array types of non-public inner classes (e.g., returning "Inner;" instead of "Inner[]") and suggests a recursive approach to handle arrays properly.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.
