> When createRootObject is called and a root object has already been created, the SDO 2.1 spec calls for an IllegalStateException but the current implementation replaces the existing root.
> Also, when either a type is not provided or when a type cannot be determined from the URI and typeName provided, a NullPointerException is thrown from org.eclipse.emf.ecore.util.EcoreUtil.create() which is not helpful to a user who is not literate in emf utilities:  an exception with a helpful error message should be provided.
> Attached are:
> a) a jar containing a new test case file for DataGraph (sdo/impl/src/test/java/org/apache/tuscany/sdo/test/DataGraphTestCase.java)
> b) a patch that corrects these problems in sdo/impl/src/main/java/org/apache/tuscany/sdo/impl/DataGraphImpl.java
