> WildcardPermissions have a caseSensitive flag that instructs the permission 
> to ignore case when comparing permissions. It's implementation of this 
> feature is kinda wasteful because it first parses the permission string into 
> a Set<String> part, THEN checks the flag and then rebuilds the part Set.
> It might be faster to check the flag first, lowercase the permission string, 
> then parse the parts. This would save creating a whole bunch of extra 
> LinkedHashSets.
