new 8cbe4ba Remove apparent Registry code duplication
8cbe4ba is described below
commit 8cbe4ba594dc41615faafb216fcb4ff3e0d8fafc
Author: remm <r...@apache.org>
AuthorDate: Thu Mar 28 15:31:09 2019 +0100
Remove apparent Registry code duplication
mserver field seems useless overall, so deprecate it. Use the resgistry
register/unregister rather than duplicated code.
