I was already using Collections.emptySet() for that case, so I just 
preserved the code.

I check with Stuart and he said either of "Collections.emptySet()" is 
used instead of "Set.of()" would be acceptable, but thought using 
"Set.of()" would be more consistent in the situation.

I'll revised the webrev accordingly.

Thanks,
