> {{ScriptBytecodeAdapter.getPropertyOnSuper}} calls {{invokeSuperMethodN(SuperType,thisObject,"getProperty", new Object[]\{"propertyName"\})}}, which calls {{thisObject.getMetaClass().invokeMethod(SuperType,thisObject,"getProperty", messageArguments, true, true)}}.  {{MetaClassImpl}}'s invokeMethod is failing to find public getProperty(String) method in class A.
> {code:groovy}
> class A {
>   def getX() { 'A' }
> }
> class B extends A {
>   def getX() { 'B' }
> }
> println new A().getProperty("x") // prints "A"
> println new B().getProperty("x") // prints "B"
> println ScriptBytecodeAdapter.getPropertyOnSuper(A, new B(), "x") // MissingMethodException: No signature of method: B.getProperty() is applicable for argument types: (String) values: [x]
> {code}
> Also, the message indicates that B is the type that was searched; it should display A.
> I found a similar result for {{ScriptBytecodeAdapter.getFieldOnSuper}} in GROOVY-9608.  I think there is something wrong with the cached super information in MetaClassImpl.  https://github.com/apache/groovy/blob/0b886e910bbb0e75aae527fae2cab0ec4f096bf2/src/test/groovy/bugs/Groovy9608.groovy#L53
