- Typos in Javadocs (./build.sh spellcheck finds this)
- Use private fields where possible
- Fix Javadoc with something that isn't a sentence
- Fix Javadoc without an actual comment
- The workaround 'clazz' instead of 'class' is not needed for 'dateClazz'
- Javadoc for parameters is inconsistent / incorrect
- Javadoc: undocumented return
- Javadoc comments are usually lowercase except for sentences
