I also tried to use `AUTO_CONSUME` schema to consume messages from C++
client now.
```java
final String topic = "ProtobufSchemaTest-testEndToEnd";
try (PulsarClient client =
PulsarClient.builder().serviceUrl("pulsar://localhost:6650").build()) {
Consumer<GenericRecord> consumer =
client.newConsumer(Schema.AUTO_CONSUME())
.topic(topic)
.subscriptionInitialPosition(SubscriptionInitialPosition.Earliest)
.subscriptionName("my-sub-auto-consume")
.subscribe();
while (true) {
Message<GenericRecord> msg = consumer.receive(1,
TimeUnit.SECONDS);
if (msg == null) {
break;
}
try {
DynamicMessage message = ((GenericProtobufNativeRecord)
msg.getValue()).getProtobufRecord();
Descriptors.FieldDescriptor fieldDescriptor =
message.getDescriptorForType().findFieldByName("testEnum");
if (fieldDescriptor == null) continue;
System.out.println("enum value: " +
message.getField(fieldDescriptor));
} catch (ClassCastException e) {
System.out.println(" failed to convert value to
GenericProtobufNativeRecord: "
+ e.getMessage());
}
}
}
```
The output is
```
enum value: FAILOVER
```
So it works well now.
