The static functions in CollectionUtils are substitutes for the
Multi-collections in Guava. So, to substitute Guava, you have to
rewrite the callers to actually use Multiset (or whatever) and not
need these functions at all. That could get fiddly. So keeping this
class in the bridge seems reasonable to me to give us more
flexibility.
