Remko Popma commented on LOG4J2-704:
------------------------------------
Thanks for pointing this out! I did not look at the stack trace above carefully.
Now that I think about it, we could make this a little user-friendlier by
checking if the URI is absolute or not before trying to convert it into a URL
(which will fail if URI is relative). If we know we can't turn it into a URL
anyway, we can log a FileNotFoundException: configLocation + " not found in
file system or in classpath" and return null.
