title: How to drop and create schema multiple times?
body: <p>I am trying to drop-and-create tables multiple times using JPA/EclipseLink (2.5.1) on a JUnit test by calling <code>createEntityManager</code> on an <code>EntityManagerFactory</code> instantiated multiple times. However, the schema is dropped/created only once. How to make EclipseLink drop/create the schema every time?</p>
  
  <p>My ultimate goal is to have the db tables in a known state (i.e. empty) for each test. Is there a better way to do that?</p>
