Issue with methodMissing using a innerClass as closure delegate

[Fernando Ariel Niwes Naufal <fe...@soluciones3f.com.ar>]

I am not sure if the following code should, or should not work. As right
now, with Groovy Version: 2.4.3 JVM: 1.8.0_31 Vendor: Oracle Corporation
OS: Mac OS X does not.

    class OuterClass {
        class DelegateClass {
            def calls = [:]
            def methodMissing(String value, args) { calls[value] = args;
return this }
        }

        def run() {
            def closure = { method1 'calling1' method2 'calling2' }

            def delegate = new DelegateClass()
            closure.delegate = delegate
            closure()

            return delegate.calls
        }
    }

    assert new OuterClass().run() == [method1: ['calling1'], method2:
['calling2']]

The same code, but with DelegateClass as a independent class does works
correctly.
Even more, if I replace methodMissing with two methods called method1, and
method2 does works correctly too.

Seems like a bug to me (specially because it fails only with methodMissing)
but I am not sure.

As I understand it, methodMissing / propertyMissing don't really work on
inner classes as things are currently designed.  You might find these

At some point we might improve the implementation, but I doubt it'll be any
time soon.
