Description

We have ~18 errors related to malformed HTML in Javadoc and missing Javadoc in package-info files (for some reason other kinds of missing Javadoc are reported by JavadocType check). I'll replace missing Javadoc with TODO: Document, so that we can enforce JavadocStyle check and stop other kinds of issues under this check creeping back in the code (like the "First sentence should end with a period." one)
