> The below code cannot be serialized by Avro.
> {code}
> class Leaf <P, Q> {
>   P p;
>   Q q;
> }
> class Root {
>   Middle1 m1;
>   Middle2 m2;
>   Middle3<Integer> m3;
> }
> class Middle1 {
>   Leaf <Integer, Long> foo;
> }
> class Middle2 {
>   Leaf <String, String> foo;
> }
> class Middle3 <P> {
>   Leaf <P, P> foo;
> }
> {code}
> This is because when generating the schema, only the current class is used to generate the schema.
> The parent class' context is missing in ReflectData#createSchema() functions where the actual type-information is actually present.
> Please see the attached test too for a simpler case.
