Code Issues Proposed changes

Avoid Collections#sort 

With the introduction of default methods in Java 8, Java finally grew a
List#sort method that can be used in place of the static
Collections#sort. Convert simple in-place sorts that need to be in-place
sorts to use this method where possible.

During the course of this change, it became obvious that many instances
of sort were just sorting a newly-created ArrayList in place. These can
be replaced with more idiomatic Stream constructions, sometimes even
eliminating a loop to populate the list.

One difference between List#sort and Collections#sort is there is no
List#sort() with no arguments; callers must always pass either
naturalOrder() or a null comparators. In this change, there were so few
remaining instances of sorting by natural order that typing
naturalOrder() didn't seem too repetitious, and it is quite readable.
