Description

The following code compiles but throws a VerifyError at runtime:

Test.groovy

class Test {

    static void main(String[] args) {
        def a = new A()
    }

    static class A {
        A() {
            def b = new B()
        }

        void sayA() { println 'saying A' }

        class B extends A {
            public B() {
                super(A.this)
                sayA()
            }
        }
    }
}

I didn't go back through versions but I tested with 2.3.0 and that shows the problem.

Caught: java.lang.VerifyError: (class: Test$A$B, method: <init> signature: (LTest$A;)V) Expecting to find object/array on stack
