[keycloak-user] Instance of Infinispan RoleAdapter

[Torsten Roemer]

Hello,

I've implemented a User Storage Provider following the Example User 
Storage Provider with EJB and JPA.

It works fine, I can fetch tokens for the users in external storage and 
now I would like to add roles to the users.
For that I have overwritten UserAdapter#getRoleMappings:

@Override
public Set<RoleModel> getRoleMappings() {
     final Set<RoleModel> roles = super.getRoleMappings();
     final RoleModel role = new RoleAdapter(this, "my-role-id", 
"my-role-name");
     roles.add(role);

     return roles;
}

RoleAdapter is my own minimal implementation of RoleModel.

While this works, there are now many calls to getUserById() which I 
think is because my RoleModel implementation is not cached.
I suppose this could be solved by using 
org.keycloak.models.cache.infinispan.RoleAdapter but how can I create an 
instance of it?
In particular, I have trouble of getting an instance of 
RealmCacheSession that needs to be passed to the constructor.

Cheers,
Torsten
