Description

This is a spin-off of LUCENE-10312.

Constants and methods in those classes are exposed to the outside packages; we should be able to limit the visibility to private or, at least to package private.

This change breaks backward compatibility so should be applied to the main branch (10.0) only, and a MIGRATE entry may be needed.

Also, they seem unchanged since 2008, we could refactor them to embrace newer Java APIs as we did in https://github.com/apache/lucene/pull/540.
