In Eclipse Jetty, across various versions of `jetty-security`, and `jetty-eeN-security`, two or more security constraints with the same http-method-omission set, and no url-patterns, are not combined properly per Jakarta Servlet Spec. Resulting in later http-method-omission sets overriding previous constraints with the same http-method-omission set.
