It is working correctly.

This is the ABNF for the query component:

   query = *( pchar / "/" / "?" )

   pchar = unreserved / pct-encoded / sub-delims / ":" / "@"

   unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

   pct-encoded = "%" HEXDIG HEXDIG

   sub-delims = "!" / "$" / "&" / "'" / "(" / ")"
               / "*" / "+" / "," / ";" / "="

(The "#4" at the end is the fragment component of the URI and is not
part of the query component.)

But i think there could be a benign encoding issue using the UriBuilder:

   System.out.println(
     UriBuilder.fromUri("http://host/").
       queryParam("str", "af,yt!6 p#4").build());

prints out:

   http://host/?str=af%2Cyt%216+p%234

This is because i am using:

   java.net.URLEncoder.encode

that encodes a string to the to the application/x-www-form-urlencoded
MIME format.
