How to persist LIsts of entities using JPA bindings in SwitchYard ?

Issue

• While working with JPA binding in SwitchYard, there are requirements for persisting java.util.List of some entities into database. However, modifying the service interface of the camel-jpa-binding quickstart does not seem to work.
  e.g. changing the existing service interface method from:

  void storeGreeting(Greet event);
  

  to this method instead:

  void storeGreeting(java.util.List<Greet> event);
  

• Does the JPA binding of SwitchYard supports Arrays of entities or collection of entities?
