add-classpath does not check whether the given url (i.e. anything coercable via io/file) exists.
This complicates debugging of ClassNotFoundException which were due to a nonexistent url being added to the classpath.
If there is no use case that must work with a nonexistent url, add-classpath should be patched to throw an error for a nonexistent url.

There are some usage patterns where transient directories are used as catch-all "repositories" for classfiles to be dynamically picked up by a running application. Plus, checking for a file's existence at add-classpath-time won't help any resource resolution issues if it's deleted later.
