The interface org.hibernate.Session extends SharedSessionContract and EntityManager. SharedSessionContract extends QueryProducer.

EntityManager has:

Query createNativeQuery(String var1, Class var2);

QueryProducer has:

<R> NativeQuery<R> createNativeQuery(String var1, Class<R> var2);

These two methods have the same erasure and so implementing the interface Session has so far been impossible. Obviously, it can be done, but I would really appreciate it if someone could explain how.

Thank you,

As demonstrated by Hibernate 5.2, this works because org.hibernate.query.NativeQuery extends javax.persistence.Query.

Therefore, both the following queries are valid:

Interesting, but not helpful. That explains why it can work, but not how to make it work. I've tried many approaches to declaring createNativeQuery, but everything I've tried so far gets a syntax error of one kind or another. What would a valid declaration for createNativeQuery actually look like?

Why do you want to implement the Hibernate Session anyway? What's your use case?

It's a mock as part of my unit testing. It has worked fine for me up until I tried to update from 5.0.5 to 5.2.5.

Check out this Unit Test from hibernate-infinispan module. It works just fine on the master branch (5.2.5).

The test mocks the Hibernate Session without any issue.
