Hi Andrej,

thanks for your remarks; see below for a comment.

In addition, I need an upper-case Review, please.

I know that setting the field to -1 does not hinder serialisation. The comment was intended to make clear that no serialisation of instances of this class will ever happen. I'll make that more clear. Omitting the field is not possible; the compiler will complain. Having serialVersionUID is enforced in the build.
