It seems like that would allow you to set all the values directly in the declaration up on line 49, would remove the need for the static block and I think you could even declare validTypes final, couldn't you?  And any new additions to the set could simply be added and not worry about setting an accurate count in the constructor.

I wondered about an approach like this. I'll push another commit with these changes.
