Description

When trying to initialize an object of an inner class, from the constructor of it's containing class, a java.lang.VerifyError is thrown. This code worked fine in Java, but when I switched to Groovy, it throws the VerifyError.

Stacktrace:

java.lang.VerifyError: (class: page_objects/Login$LoginNavigationBar$ExploreDestinationsDropdown, method: <init> signature: (Lpage_objects/Login$LoginNavigationBar;)V) Expecting to find object/array on stack

Offending Code:

class LoginNavigationBar
    {
        ExploreDestinationsDropdown exploreDestinationsDropdown

        private LoginNavigationBar()
        {
            // THIS IS THE LINE THAT PRODUCES THE ERROR
            exploreDestinationsDropdown = new ExploreDestinationsDropdown() 
        }

        class ExploreDestinationsDropdown extends NavigationBarDropdown<ExploreDestinationsDropdown>
        {
            private ExploreDestinationsDropdown()
            {
                super(Login.this.sw, 0)
            }
        }
}

It also may be useful to know that LoginNavigationBar itself is an inner class of Login. So ExploreDestinationsDropwown is an inner class of an inner class. Also, the constructor for LoginNavigationBar is being called from the constructor of Login, the enclosing class.
