I've often wished that CharSequence had getChars methods, as many of

In jdk8 with default methods, this is possible!
This will make some of the String code a little nicer and more efficient.
Here's a preliminary patch in this direction, that overlaps with some
of the work done in
6206780: (str) Forwarding append methods in String{Buffer,Builder} are
inconsistent
Summary: update StringBuilder & StringBuffer to consistently handle
forwarding to AbstractStringBuilder. Some additional cleanup (removal
of refs to sub-classes from AbstractStringBuilder)

If we have consensus that this is a good idea, I can flesh this out.
It's come up a few times and I agree it's worth trying out.
You should probably add CharBuffer to the list to look at it. At least
for the 3-arg getChars, then it will need consideration as to whether it
works as relative bulk get (which it would if not overridden). Also the
5-args getChars will treat srcBegin/srcEnd as relative to the current
position as it stands.
