Special notes to reviewer

One minor remark regarding a checkstyle warning

[schwepmo]

There is a new Checkstyle warning regarding the positioning of this method, which I don't quite get.
Moving this method further down will probably fix it though.

I guess because I put it between getType(V2xMessageTransmission interaction) and getType(V2xMessageReception interaction). I re-ordered the methods.
