Suggestion:
private static final ServerRequestPair
HTTP1 = ServerRequestPair.of(Version.HTTP_1_1, false),
HTTPS1 = ServerRequestPair.of(Version.HTTP_1_1, true),
HTTP2 = ServerRequestPair.of(Version.HTTP_2, false),
HTTPS2 = ServerRequestPair.of(Version.HTTP_2, true);
This coding style can be considered for declaring multiple consecutive fields
of the same type.
