Subject: Only a set is needed, if only found users are added. this way, the EJB gets more... 
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=29b38b325196603a8e65d702c92aff31d1eb1e9e;p=jbonuscard-lib.git

Only a set is needed, if only found users are added. this way, the EJB gets more calls on invalid numbers, but else the Map would be flooded with junk entries. Again blue or red pill ...
