AFAIK, no.

Well, for a start it can break code that relies on being able to dynamically load classes and resources. It is also possible this kind of thing could be used to break security sandboxes.

Why are you considering doing this?

As you can't the question is pointless.

Answer 3

You could use URLs with URLStreamHandlers which shutdown, if you were desperate. That may not affect load classes and resources from already open Jar files.

I don't see a particular problem with this. Unlike addURL where a class may not be on the set of URLs when first asked for, and cannot be subsequently added.
