Yes, they are generally more error-prone than using URI, since they
don’t encode illegal characters in the various components.

> And if we end up not using the URL constructors, then I still think it would be nice to have a test library, since it's easy to forget to add the "[]". Unless we fix up all the existing tests and you'll be sure to catch any future bad uses of the loopback address in URLs in tests :)

Test library support would be fine. ( it would require some additional
jtreg tags and imports, but that is not a reason to avoid it )

If we do add test library support, then maybe we could take the
opportunity to construct it in a way where we could gain experience for
future possible projects, e.g.

   URIBuilder.newBuilder()
          .scheme("http")
          .host("www.example.com")
          .path("/sample")
          .query("version=12")
          .build()
          .toURL();
          
With suitable encoding / raw variants. Daniel has prototyped something
similar for the URI update investigation work.
