- **Type Safe** - Comprehensive use of generics and modern Java type system features

### Additional Components
- **Text Processing** (`org.codelibs.core.text`) - JSON utilities, tokenization, decimal formatting, and text manipulation
- **Logging Abstraction** (`org.codelibs.core.log`) - Flexible logging system supporting JCL (Jakarta Commons Logging) and JUL (Java Util Logging)

    Some tests need reflective access to the internals of these packages. It is only the

    We could consider arranging things so that only the tests we know need this would get
    the add-opens. Right now that doesn't seem worth the effort, though.
