Add part in StructuredClassifier throw an exception [message #625776]

hi,

Here is my testcase:

@Test
public void testAddPart() {

Class cl = UMLFactory.eINSTANCE.createClass();
Property p = cl.createOwnedAttribute("pp", null,
UMLPackage.eINSTANCE.getProperty() );
cl.getParts().add(p);

}

An UnsupportedOperationException is thrown at the last line.

I debuged the code, found the container of the Part is PartEList, which
cannot add new element into it. Someone please tell me why we use this
kind of mechanism.
