Apache pulsar Encryption failed using ecdsa

Trying to send encrypted messages from producer but got this exception:

org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.ExecutionException: org.apache.pulsar.client.api.PulsarClientException: java.lang.NoSuchMethodError: 'org.apache.pulsar.shade.io.netty.buffer.ByteBuf org.apache.pulsar.client.api.MessageCrypto.encrypt(java.util.Set, org.apache.pulsar.client.api.CryptoKeyReader, java.util.function.Supplier, org.apache.pulsar.shade.io.netty.buffer.ByteBuf)'

--------------------------------------------------------------------------------------------------
Followed the Encryption from the apache pulsar documentation and the sampleProducerConsumerTest class from pulsar client.
Generated a public key and the private key 
created a Pulsarclient object
--------------------------------------------------------------------------------------------------
client = PulsarClient.builder()
					.serviceUrl("pulsar+ssl:xxxxxxxxxxxxxxxxx:6651/")
					.tlsTrustCertsFilePath("src/main/resources/ca.cert.pem")
					.enableTls(true)
					.authentication("org.apache.pulsar.client.impl.auth.AuthenticationTls", authParams).build();

Producer<byte[]> producer = client.newProducer()
					.topic("persistent://tenant/namespace/nonprod-topic-1")
					.cryptoKeyReader(new RawFileKeyReader("src/main/resources/test_ecdsa_pubkey.pem", "src/main/resources/test_ecdsa_privkey.pem"))
					.addEncryptionKey("src/main/resources/test_ecdsa_pubkey.pem")
					.enableBatching(false)
					.create();

String message = "Test Messages";
			int i = 2;
			while(true) {
				i = i + 1;
				message = message + " Mesage # " + i;

				producer.send(message.getBytes());
				System.out.println("Printing the Messages " + message);
				producer.flush();
				if (i == 100) {
					break;
				}
			}
			producer.close();
			client.close();

To Reproduce Steps to reproduce the behavior:

1. Go to ' create a producer class in java. add the serviceUrl, generate public key, generate private key, use certificates for tls authentication, and make the topic as encryption enabled'
2. Click on ' run the sample producer'
3. Scroll down to ' console'
4. See error 
'org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.ExecutionException: org.apache.pulsar.client.api.PulsarClientException: java.lang.NoSuchMethodError: 'org.apache.pulsar.shade.io.netty.buffer.ByteBuf org.apache.pulsar.client.api.MessageCrypto.encrypt(java.util.Set, org.apache.pulsar.client.api.CryptoKeyReader, java.util.function.Supplier, org.apache.pulsar.shade.io.netty.buffer.ByteBuf)'

Expected behavior send message encrypted messages using ecdsa public key and private key,

Not sure how you got those errors. With 2.5.1 I get: Class not found for org.apache.pulsar.client.impl.crypto.MessageCryptoBc Which can be resolved by adding the following dependency compile group: ‘org.apache.pulsar’, name: ‘pulsar-client-messagecrypto-bc’, version: ‘2.5.1’
