This rings a bell.  I was finding URI's multi-arg constructors useless.  
Since the query string must be submitted as a unit, it must already be 
using & and =, and any special characters in it that are to be taken 
literally must already be encoded, yet the constructor treats it as 
unencoded, and adds another level of encoding.  That also goes for your 
userInfo component with an @ in it to separate user and domain.

I think the solution for me was just to use URLEncoder, concatenate the 
strings, then pass to URI.create().
