Review comment:
AutoCloseable documentation says _implementers of this interface are
strongly encouraged to make their close methods idempotent._

> There needs to be a way to execute Java-SDK pipelines against a portable job
> server. The job server itself is expected to be started up out-of-band. The
> "PortableRunner" should take an option indicating the Job API endpoint and
> defer other runner configurations to the backend itself.
