new a38e0c3 JOHNZON-364 JsonbVisibility always wins over default rules
a38e0c3 is described below
commit a38e0c3daef597bae13e0cc68548f8386272c570
Author: Mark Struberg <strub...@apache.org>
AuthorDate: Fri Feb 25 15:11:03 2022 +0100
JOHNZON-364 JsonbVisibility always wins over default rules
This partially reverts JOHNZON-250 which did remove fields as readers if a
getter exists.
Sadly this also did remove the option to keep those fields via
JsonbVisibility.
