>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 2.4.7
>            Reporter: Daniil Ovchinnikov
>
> {code}
> interface Self {
>     def bar()
> }
> @SelfType(Self)
> trait T {
>     def foo() {
>         println "foo called"
>         bar()
>     }
> }
> interface Middle extends T {}
> class C implements Middle {}
> new C().foo()
> {code}
> Above code compiles fine but fails at run time with:
> {noformat}
> groovy.lang.MissingMethodException: No signature of method: selftype.baseinterface.C.bar() is applicable for argument types: () values: []
> {noformat}
> The compilation should fail like if {{Middle}} was a trait.
