Review comment:
       ```suggestion
           String body = "[[\"getFilter\",   {}, \"#0\"]]";
   ```
   
   Would be both acceptable and more readable to me.

Review comment:
       We should be able to just pass the list of authentication strategies we 
want for Draft and RFC-8621.
   
   From there, we could craft the JMAPDraft configuration POJO and the 
JMAPRFC8621 configuration POJO  with those strategies and inject these 
strategies using a guice module override. 
   
   We would be closer to reality!
