The disappointments I had during setting up jCache workshop for BG JUG

Now this is not really disappointment with jCache spec per se as it was my first one. It is more in the Hazelcast - Payara integration.

Note
 the current version of Payara is working with Hazelcast 3.5.2. As far as I saw, the serialization implementation, which is the one that is heavily involved here, was changed a lot since then. So maybe all these issues were fixed.

So, as part of our workshop, we tried to showcase as well chapter 9 of the spec: Entry Processors. We wanted when a comment was put in our comments cache, it’s description to contain also the comment author at the end.

So we implemented our simple entry processor by the spec:

The usecase

I have this simple interface:

interface UserManager {

    User getUser(String userName, String password);

I have a user manager interface with two implementations:

interface UserManager {
  User findUserByName(String userName);
}

public class JPAUserManager {
