-----------------------------
> ScriptBytecodeAdapter.getPropertyOnSuper fails with method missing for
> getProperty

> Key: GROOVY-9609
> URL: https://issues.apache.org/jira/browse/GROOVY-9609
> Project: Groovy
> Issue Type: Bug
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 4.0.0-rc-2
>
>
> {{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.
