* Tests on invoke-super-default.
*
* Invoke-super-default is used by a subclass to defer to a default method
* implementation or to disambiguate between conflicting inherited default
* methods.
*
* Invoke-super-default appears in the source code as
* "<interface-name>.super.<method-name>(<args>)". It is compiled into an
* invokespecial instruction whose target is <interface-name>.<method-name>,
* where the interface is a direct supertype of the current class (the current class
* must directly implement <interface-name>).
*
* Invokespecial on any superinterface method will run interface method
* resolution, and then the selected method will be set to the resolved method.
* super defaults no longer check for lack of shadowing, other languages
* want this capability.

* Test validity of invokespecial on indirect superinterface's method,

* JVMS-4.9.2 Structural Constraints
* Each invokespecial instruction must name an instance initialization
* method (2.9), or must reference a method in the current class or interface,
* a method in a superclass of the current class or interface, or a method
* in a direct superinterface of the current class or interface
*
* Note: Normally javac would reject this test case complaining that,
* InDirectSuper.java:5: error: not an enclosing class: I
* interface K extends J { default public void m() { I.super.m(); } }
* ^
* However, the below test case allows us to check for this structural
* constraint on invokespecial in the JVM.

* interface J extends I { }
* interface K extends J { int m() default { return I.super.m(); } }
