NPE in ODocument creation #7150
Description
OrientDB Version: 2.2.16
Java Version: 8
It's allowed to create ODocument with className null, but if you specify null oClass - it will through NPE.
new ODocument((String)null); // It's OK
new ODocument((OClass)null); It's failing, **but in OrientDB 2.1.19 it was OK**.
