Submitting a seed/truncate request for a tile layer results in a "406, not acceptable"

Description

Try to submit a seeding or truncate request, submit, and the browser is redirected to a URL like:
http://localhost:8080/geoserver/gwc/rest/seed/topp:states

which shows a "406, unacceptable", with the following logs:

Just adding ".html" to the url seems to fix it. Do the GWC REST controllers have a concept of default format?

By the way, issue found on master, suppose it happens also for 2.12.x
