A class diagram gets corrupted when adding an association between two classes. As long as the diagram is still open everything works fine but when saving, closing and reopening the diagram the following exception occurs:

Reproducible: Always

Steps to Reproduce:
1. Create empty Papyrus Project
2. Create Papyrus model with class diagram
3. Create two classes
4. Draw association between those two classes
5. Save and close the diagram
6. Try to reopen the diagram

Eclipse modeling tools Build ID : 20100618-0524
papyrus-MDT version : 201006241830

Since last update, this happens on all class diagram with association links.
