There was a problem hiding this comment.
as far as I understand the code here, we want to resolve the T of a generic. If the T is not defined by the contextType, (because ist is no class Foo<T extends Bar>) we get to this line.
In my case, the T is bound by the function public <T extends BaseType> List<T> get() and means, that T is at least a BaseType
IMHO the type must be resolved here, so that the following code knows , that the elements in the list are BaseType or subtypes. This is later required for jackson, otherwise we have problems mentioned in this SO post.

I tried to make a unit test and a possible fix for #33968
Someone who knows more about it than me should take another look at the fix ;)
