tzulitai opened a new pull request #7818: [hotfix] [core] Clarify CompositeTypeSerializerSnapshot class signature
URL: https://github.com/apache/flink/pull/7818
 
 
   ## What is the purpose of the change
   
   Prior to this PR, the class signature of `CompositeTypeSerializerSnapshot` allowed subclasses to have raw types, while also requiring subclasses to erase types and re-cast when providing the expected serializer class in constructors.
   
   This PR fixes the signature, as well as simplify subclass implementations of the class type erasure and re-casts.
