This was done in Eclipse Neon RC1, freshly installed from the SDK

1. Install UML Designer (latest nightly - version 7.0.0.201603291431)
2. File > New > Example... > Travel Agency UML
3. Expand the new project so a session opens
4. Delete the TravelAgency project

The following exception is thrown. Might be linked to bug 494128 that happens on step 3.
