jetty: Improper validation of HTTP/1 content-length

A flaw was found in Jetty that permits a plus sign + preceding the content-length value in a HTTP/1 header field, which is non-standard and more permissive than RFC. This issue could allow an attacker to request smuggling in conjunction with a server that does not close connections after 400...
