When putting a slightest delay in the repeated call, the error goes away, e.g.
while (true) {
String payload = String.valueOf(System.currentTimeMillis());
publisher.publish(PubsubMessage.newBuilder().setData(ByteString.copyFromUtf8(payload)).build());
System.out.println(payload);
// or Thread.sleep(100L)
