Hello,
I am currently a bit puzzled by a piece of code which broke by relying on
HttpServletRequest.getParameter(String paramName) returning an empty String
for parameters without a value - what happens on a recent Jetty is
getParameter returns null instead.
Upon further investigation I found the cause is two values are actually
parsed and returned by getParameterValues [null, ""]) and the first (null)
is returned by getParameter.
E.g. for the Query String "?param1=value1¶m2=value2¶m3="
getParameterValues("param3") returns [null, ""] and getParameter("param3")
returns null.
What is the rationale behind getParameterValues returning two values?
Has this behaviour changed "recently" and could somebody please give me a
pointer to the specification?
Thanks a lot and best regards, Clemens
