Joe,

I think java.util.Objects could benefit from the "final" modifier. Since its constructor always fails, there is no reason to subclass it (i.e., super constructor always fails). I believe Josh's "Effective Java" book makes such a point about static utility classes. Paul

Hello.

Classes with only private constructors, like j.u.Objects, are effectively final. Adding final is harmless but unnecessary in these cases. The platform is a bit inconsistent here; j.u.Collections is not marked final while j.l.Math is. In practice, it doesn't matter very much; I'll consider final-izing j.u.Objects on the next round of edits.
