Thanks Naoto. Addressing review comments. As we discussed offline, as we got CSR approval, we'll keep the javadoc in @param as a style choice. Added NPE for catalog; Fixed the redundant "returns"; Added error report. 
Furthermore, after consulting with Daniel, modified the Util method with URL instead of URI/Path as the former is a more straight-forward solution requiring no additional manipulation.
