    Horizontal inheritance is also implemented now (3.0M6). However, you should watch the jira task [4] to see when vertical inheritance is being worked on. In the short term, you may be able to implement what you need using the other two ways to model inheritance; for the most part, your Java code will not change when you change your database implementation of how the inheritance is represented.
