Review comment:
It behaves as expected with embedded mode in the job server and with default
class loading behavior on the remote cluster (i.e. there won't be caching). The
remaining test would be the augmented class loading described on
https://beam.apache.org/contribute/portability/#status - which should also
work, since it is parent first.
