The procedure “parse-rfc-822-date” in the module (web http) is a bit too
strict as it rejects dates in which the hour field is a single digit
without zero-padding.

A date like this will be rejected:

    Sun, 06 Nov 1994  8:49:37 GMT

Whereas a date like this is accepted:

    Sun, 06 Nov 1994 08:49:37 GMT

The only difference is the leading zero in the timestamp.

Dates like the former are produced by maven (see “Last-Modified”
header):
