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. Camel version 2.16.1. Am I missing something?
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 {
@Test
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}");
}
});
context.start();
Exchange incomingExchange = new DefaultExchange(context);
incomingExchange.setProperty("myObject", new B() {
});
Exchange result = context.createProducerTemplate().send("direct:camelSimpleDoesNotSeeDefaultMethod", incomingExchange);
Assert.assertNull(result.getException());
}
public static interface A {
public default String defaultMethod() {
return "default method result";
}
}
public static interface B extends A {
}
}
