---------------------------------
Hi,
Sorry about the delay in getting back to you - I started a new job and it's
been hectic.
I can confirm that getAllMethods is finding the default method. However, that's
not solving my problem - mainly because I didn't give you some important
context.
Our code is actually calling Ognl.getValue which eventually calls "callMethod"
which calls "getMethods" - so while I can confirm that getAllMethods does
work, I can't actually use the fixed method!

> Project: Commons OGNL
> Issue Type: Bug
> Components: Core Runtime
> Affects Versions: 3.0
> Environment: Java 8, OSX, likely all environments tho.
> Reporter: Tim Wright
> Fix For: 4.0

>
> Hi,
> I'm a contributor to an open source automated test framework called
> "Concordion". We use OGNL internally to evaulate test specifications. One of
> our users has reported a bug where Concordion cannot call default interface
> methods. We've traced the problem to OGNL - the OgnlRuntime.getMethods method
> is not returning default implementations of interface methods. We've verified
> the behaviour in OGNL versions 2.6.9 and 3.0.9.
> Consider the following interface and junit test file. The test fails. But it
> probably should not.
> {code:java}
> // INTERFACE
> package org.concordion;
> public interface InterfaceWithDefaults {
> default public void defaultMethod() { }
> }
> {code}
> {code:java}
> // TEST CLASS
> package org.concordion;
> import ognl.OgnlRuntime;
> import org.junit.Test;
> import static org.junit.Assert.assertNotNull;
> public class TestDefaultMethods implements InterfaceWithDefaults {
> @Test
> public void testDefaultMethod() {
> defaultMethod();
> assertNotNull(OgnlRuntime.getMethods(TestDefaultMethods.class,
> "defaultMethod", false));
> }
> }
> {code}
