The reason for this is that the MBW should have full control on whether a Content-Length header is set or not and the JAX-RS runtime should not set this.

Yes, if they can set it, set it.

I fixed a bug a few months ago where our container set the
Content-Length header based on MBW.getSize() and we had gzip encoding
on, so the value Content-Length ended up being wrong.
