Description

Example:

@groovy.transform.CompileStatic
class A {
    private int bar() { 123 }
    
    class B {
        int testInner() { new C().barInner() }
        
        class C {
            int barInner() { bar() }
        }
    }

    int test() {
        new B().testInner()
    }
}
assert new A().test() == 123

The code above fails with the following error at runtime:

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'A$B@4c1d9d4b' with class 'A$B' to class 'A'

This occurs because the bridge method owner for an 'implicit this' private method call is assumed to be the immediate outer class.
