Exactly, the same information but more prominent.

I personally dislike that one too in this valve.

In my opinion, the following should happen:

If message is not given: Message should be from
https://tools.ietf.org/html/rfc2616#section-6.1.1 as per status code short name
and description should be a copy of the first sentence of the RFC description.
Maybe just as HTTPd does.
If message is given: Display message and show RFC description too.

Stack trace should be left as is.

It might make sense to limit the message length in the first line to n chars
and show the entire message in the message line. But if and only if the message
is to0 long. Otherwise the message line should be omitted.
