…newInstance() Class.newInstance() has been deprecated since Java 9 because it propagates exceptions thrown by the nullary constructor, including checked exceptions. The replacement getDeclaredConstructor().newInstance() wraps such exceptions in an InvocationTargetException. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

There seems to be 4 more uses of Class.newInstance(). I will go ahead and make those changes.
