commit d7a770acf8761c42958b56d6ce4864e32f8a9957
Author: remm <r...@apache.org>
AuthorDate: Tue Apr 16 14:44:06 2019 +0200
Another round of cleanups
Almost no code change except removing needless exception nesting in
cancelledKey. Add a little i18n since a string was used way too often to
mean something. Some formatting and variable names.
