Alexander Klimetschek commented on SLING-2819:
----------------------------------------------
map() expects a path for the 2nd argument, so I think it should simply throw an
IllegalArgumentException "not a path" in case uri.getPath() returns null or
simply return the original string unmodified. Depending on what we want.
> NPE in ResourceResolverImpl.mangleNamespaces when attempting to map
> http://example.com
