This isn't necessary.  Everyone who does a get or a put against the
byName map already is forming a lower case key string.  I'd rather
keep the lookup O(1) than O(log N), especially if the code has a
ton of .toLowerCase() calls in it to normalize the keys.

If you are going to change it to a TreeMap with a custom Comparator
then maybe we should cleanup the code that operates on byName so it
can use the original input strings, instead of the .toLowerCase()
forms.

For now I'm going to apply your patch without this one hunk.  If you
want to switch to a TreeMap lets also cleanup the get/put calls.
