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.

Answer
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.
