@tillrohrmann I added a comment that only protocols are supported which are
supported by the `URLClassLoader`. The parameter above is Java standard.

> Currently, there is no option to add customs classpath URLs to the
> FlinkUserCodeClassLoader. JARs always need to be shipped to the cluster even
> if they are already present on all nodes.
> It would be great if RemoteEnvironment also accepts valid classpaths URLs and
> forwards them to BlobLibraryCacheManager.
