Original description

When querying my database before I've actually saved any instances, raises the exception:

com.orientechnologies.orient.core.exception.OCommandExecutionException: Class DOG was not found
    at com.orientechnologies.orient.core.sql.OCommandExecutorSQLSelect.execute(Unknown Source)

Where I would instead expect an empty result set. 

I imagine this is actually a Schema error (which isn't clear from the message), and is because the schema isn't actually created until an object is saved. IMO I would would like the schema's to be created when I run the 

  db.getEntityManager().registerEntityClasses

command. That way I could safely query it, without anything blowing up...

So I see two problems here:
1. time at which schema is created causes issues
2. error message when querying a type that hasn't been created is not clear.

Perhaps there is another way that I can trigger the automatic build of my schema, without saving an issue?
