Reading from a Pub/Sub Lite subscription using PubsubLiteIO fails with
DataflowRunner. It works in DirectRunner.
```
import org.apache.beam.sdk.io.gcp.pubsublite.PubsubLiteIO;
//..
pipeline
.apply("Read
From Lite", PubsubLiteIO.read(subscriberOpitons))
.apply("Convert and print",
MapElements.into(TypeDescriptors.strings()).via(
(SequencedMessage sequencedMessage) -> {
String data =
sequencedMessage.getMessage().getData().toStringUtf8();
LOG.info("Received: " + data);
return data;
}
));
```
```
java.lang.UnsupportedOperationException: BundleFinalizer unsupported by
non-portable Dataflow.
