Anton Sulim created CAMEL-11178:

             Summary: Default method is invisible during Camel Simple evaluation
                 Key: CAMEL-11178
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.16.1
            Reporter: Anton Sulim

Issue can be reproduced with below unit test, I have not found it in tracker. 
Essence: interface A has default method, interface B extends A, default method is invisible
during Simple language evaluation. 

import org.apache.camel.CamelContext;
import org.apache.camel.Exchange;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.impl.DefaultExchange;
import org.junit.Assert;
import org.junit.Test;

public class DefaultMethodIsInvisibleTest {

    public static interface A {
        public default String defaultMethod() {
            return "default method result";

    public static interface B extends A {

    public void camelSimpleDoesNotSeeDefaultMethod() throws Exception {
        CamelContext context = new DefaultCamelContext();
        context.addRoutes(new RouteBuilder() {
            public void configure() {
                from("direct:camelSimpleDoesNotSeeDefaultMethod").log("Result of default method
invocation is ${exchangeProperty.myObject.defaultMethod}");

        Exchange incomingExchange = new DefaultExchange(context);
        incomingExchange.setProperty("myObject", new B() {

        Exchange result = context.createProducerTemplate().send("direct:camelSimpleDoesNotSeeDefaultMethod",
