[GROOVY-7930] @SelfType in hierarchy with an interface in the middle

• Type: Bug

Description

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()

Above code compiles fine but fails at run time with:

groovy.lang.MissingMethodException: No signature of method: selftype.baseinterface.C.bar() is applicable for argument types: () values: []

The compilation should fail like if Middle was a trait.
