This is not portable, and fails depending on the JVM used, see https://www.oracle.com/java/technologies/faq-sun-packages.html:

> The sun.* packages are not part of the supported, public interface.
> A Java program that directly calls into sun.* packages is not
> guaranteed to work on all Java-compatible platforms. In fact, such a
> program is not guaranteed to work even in future versions on the same
> platform.

Instead of matching a specific keyspace name, --exclude-keyspaces now
takes a regex as an argument; every keyspaces which match the regex will
be ignored.

This is not entirely backward compatible, as
`--exclude-keyspaces=foobar` will exclude `foobar`, but also
`some_foobar_keyspace` as well.
