  A workaround for customers on 7.5.0.2:
  Add the following code after calling session.clear();  Note
  that you must replace the strings "https://myserver/ram",
  "username", and "password" with the values for your server.
  The "session" variable is the variable you use for
  RAMSession.
   try {
    Field resourceSetField =
  session.getClass().getDeclaredField("fResourceSet");
    resourceSetField.setAccessible(true);
    resourceSetField.set(session, null);
    Field serverToLocalEMFURIResourceMapField =
  session.getClass().getDeclaredField("fServerToLocalEMFURIRes
  ourceMap");
  
  serverToLocalEMFURIResourceMapField.setAccessible(true);
  
  serverToLocalEMFURIResourceMapField.set(session, new
  HashMap());
    Method createClient =
  session.getClass().getDeclaredMethod("createClient", new
  Class[]{String.class, String.class, String.class,
  String.class});
    createClient.setAccessible(true);
    createClient.invoke(session,
  "https://myserver/ram/", "username", "password", null);
       } catch (SecurityException e) {
    e.printStackTrace();
       } catch (NoSuchFieldException e) {
    e.printStackTrace();
       }  catch (IllegalArgumentException e) {
    e.printStackTrace();
       } catch (IllegalAccessException e) {
    e.printStackTrace();
       } catch (NoSuchMethodException e) {
    e.printStackTrace();
       } catch (InvocationTargetException e) {
    e.printStackTrace();
       }
