DataGraph.createRootObject implementation does not match 2.1 spec and also is
not helpful when given bad parameters
-------------------------------------------------------------------------------------------------------------------
Key: TUSCANY-1062
URL: https://issues.apache.org/jira/browse/TUSCANY-1062
Project: Tuscany
Issue Type: Bug
Components: Java SDO Implementation
Affects Versions: Java-M2
Reporter: Paul Golick
Fix For: Java-M3
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
