Original description

Error produced using Version 0.9.24-SNAP
<b>What steps will reproduce the problem?</b>
1. Create new ODatabaseGraph and open it.
2. Create an OClass (Entity) using schema api and save.
3. Create an OClass (Person) that inherits from above class (Entity) using schema api and save.
4. Create a vertex from OClass (Person) in step 3
5. Run query on database.
    Runs as expected!
6. close database
7. Open same database
8. Create a vertex from OClass (Person) in step 3
9. Run query on database.
    Fails with the following error:
