>                 URL: https://issues.apache.org/jira/browse/FLINK-7450
>             Project: Flink
>          Issue Type: Bug
>          Components: Type Serialization System
>    Affects Versions: 1.3.2
>            Reporter: Timo Walther
>
> The TypeExtractor does not correctly handle POJO fields with bounded generics.
> For example:
> {code}
> public class Foo<SomeKey extends BarKey> implements Serializable {
>     public SomeKey someKey;
>     public Foo() {}
>     public Foo(SomeKey someKey) {
>         this.someKey = someKey;
>     }
> }
> {code}
> Is identified as:
> {code}
> PojoType<org.apache.flink.streaming.examples.wordcount.WordCount$Foo, fields = [someKey: GenericType<java.lang.Object>]>
> {code}
> So even though the reflection field has a type, the type information only describes a Object class.
