Hello again. I am executing this code:
static public void testFullSave(ResourceSet rs, String sourceFile,
String resourceName, boolean legacyMode) {
Resource r = rs
.getResource(URI.createFileURI(new File(sourceFile)
.getAbsolutePath()), true);
List<EObject> roots = r.getContents();
CDOSessionConfiguration sessionConfiguration = initialize();
if (legacyMode) {
CDOUtil.setLegacyModeDefault(true);
}
CDOSession session = openSession(sessionConfiguration);
long l = System.currentTimeMillis();
CDOTransaction transaction = session.openTransaction();
CDOResource resource = transaction.getOrCreateResource(resourceName); //$NON-NLS-1$
resource.getContents().clear();
resource.getContents().addAll(roots);
try {
transaction.commit();
System.err.println("FULL SAVE TIME: "
+ (System.currentTimeMillis() - l));
} catch (CommitException e) {
System.err.println("FULL SAVE TIME UNTIL ERROR: "
+ (System.currentTimeMillis() - l));
e.printStackTrace();
}
transaction.close();
session.close();
System.exit(0);
}
which stores a model in a CDO Hibernate 4.0 repository over MySQL. The same code and example model worked fine in CDO 4.0 but now it throws a ClassCastException on the server:
Hibernate: insert into `cdoresourcenode` (e_version, resource_id, container_id, `name`, `dtype`) values (?, ?, ?, ?, 'CDOResource')
Hibernate: insert into `core_physicalelement` (resource_id, container_id, version, `path`, `isreadonly`, dtype) values (?, ?, ?, ?, ?, 'core.IJavaModel')

core_physicalelement is the table that corresponds to the abstract superclass of the root of model.
Since both the source XMI model and the generated Java classes worked correctly with CDO 4.0 and other EMF software I assume that there is nothing wrong with them. Could it be a problem of the generated Hibernate Mapping?
I have also generated a Hibernate Mapping with the org.eclipse.emf.cdo.examples.hibernate.client.GenerateHBMTest test class. The relevant excerpt of the mapping is:

IJavaModel extends IJavaElement and PhysicalElement and is the model root's metaclass.
Thanks in advance.

Hi,
I am on holiday/traveling, but hope to take a look later today.
