java.lang.AbstractMethodError occurs while trying to implement call inbound of nexmo SDK through rabbitMQ

Question

I am trying to integrate call inbound feature using nexmo java SDK to my spring MVC project with help of rabbitMQ. But I keep on getting the exception below

[WARN ] 2021-01-26 14:52:26.913 [org.springframework.amqp.rabbit.config.ListenerContainerFactoryBean#6-9]   ConditionalRejectingErrorHandler - Execution of Rabbit message listener failed.

RabbitMQ Listener class where call inbound logic is implemented.

@RabbitListener
public class VoiceCallListener {
    public void listen(VoiceCallPojo voiceCallPojo) {
        NexmoClient client = NexmoClient.builder()
                .apiKey(API_KEY)
                .applicationId(APPLICATION_ID)
                .privateKeyContents(PRIVATE_KEY).httpConfig(HttpConfig.defaultConfig())
                .signatureSecret(SECRET_KEY)
                .build();
        Ncco ncco = new Ncco(
         TalkAction.builder(voiceCallPojo.getMessage()).voiceName(VoiceName.ADITI).build()
        );
        CallEvent result = client.getVoiceClient().createCall(new Call(voiceCallPojo.getCallNumber(),FROM_NUMBER, ncco));
    }

This has nothing to do with spring-rabbit; it is an incompatibility between the two library versions you are using and will happen when called from any of your code. See the javadocs for AbstractMethodError.

/**
 * Thrown when an application tries to call an abstract method.
 * Normally, this error is caught by the compiler; this error can
 * only occur at run time if the definition of some class has
 * incompatibly changed since the currently executing method was last
 * compiled.
 *
 * @author  unascribed
 * @since   1.0
 */

You need to find out which versions are compatible.
