Description

When setting parameters in URIBuilder, the keys and values are double-escaped: once in URIBuilder.build(), and again in URI.appendSchemeSpecificPart(). Example:

URIBuilder ub = new URIBuilder("http://www.google.com/");
ub.addParameter("foo=bar", "baz&qux");
ub.build(); // http://www.google.com/?foo%253Dbar=baz%2526qux

In order to avoid this problem, URIBuilder.build() should use URI's one-argument constructor, which does not try to do extra escaping.
