I was looking at a list of RJ designations the other day, and I realised that RJ-45 actually calls for a KEYED 8p8c (as do most of the other RJ-4x's),
as opposed to the UNKEYED 8p8c used for ethernet, RJ31, 37, 61, etc..

So the RJ-45 == Ethernet is even more incorrect than we thought.. it's not only the wrong term for the connector, it's not even the right connector..
