Description

I am having a problem with serialization of an SDO2 datagraph

Using java serialization (ObjectOutputStream.writeObject()), I receive the following exception:

java.lang.UnsupportedOperationException

Note, the same test case works with SDO 1 and is currently available in SVN (org.apache.tuscany.das.rdb.test.SerializationTests)
