Eric Milles commented on GROOVY-8283:
-------------------------------------
Dynamic and static compilation both select the public accessor of A. It is not
a simple matter of "protected B ff" shadows "protected A ff". There is some
confusion in STC because it searches class by class up the type hierarchy and
stops at the field of B.
[~paulk] [~blackdrag] Do you think there is anything left to do here? I
suppose STC inference could match the runtime, but there are other instances of
this happening since property resolution is actually split into two parts
({{StaticTypeCheckingVisitor}} and {{StaticTypesCallSiteWriter}}). GROOVY-6277
is one example. Here is another:
