True and that is a potential for improvement. All I am saying is that this
module brings a dependency that may have also some transient dependency for
something that is not very well utilized. You are only using 2 classes from it
and those two classes have adequate equivalents in JDK. Always think about the
distribution of a NAR and its size. Rule of thumb, _the thinner the better_.
