I do not think it would be appropriate to have such a method in `java.net.URI`. Dealing with `URLStreamHandler` is advanced usage and is not something that a regular developer will need to do, and it is better if it isn't too prominent.

I see your point.  It may be more appropriate if URI.toURL was designed as URL.fromURL.

I was wondering to have application developers a consistent way to get an URL instance.  Now there are two methods in different classes URI.toURL and URL.fromURI.  It might be easier to use the old URI.toURL form.

Never mind, it is just my personal preference.  It is fine to me to have a new URL.fromURI method.
