Minimal reproduce step

final String topicName = "non-persistent://public/default/test";
admin.topics().createPartitionedTopic(topicName, 4);
TopicName partition = TopicName.get(topicName).getPartition(4);
@Cleanup
Producer<byte[]> producer = pulsarClient.newProducer()
          .topic(partition.toString())
          .create();

What did you expect to see?

The non-existent partition shouldn't be created.

"persistent://public/default/test-partition-0"
"persistent://public/default/test-partition-3"
"persistent://public/default/test-partition-2"
"persistent://public/default/test-partition-1"

{
"partitions" : 4
}

What did you see instead?

The non-existent partition creates success.

"persistent://public/default/test-partition-0"
"persistent://public/default/test-partition-4"
"persistent://public/default/test-partition-3"
"persistent://public/default/test-partition-2"
"persistent://public/default/test-partition-1"

{
"partitions" : 4
}

Anything else?
