Having previously opened 2 files within a project, then restarted eclipse, and deleting the project causes an exception in the previously uninstantiated editor:

org.eclipse.core.runtime.CoreException: The file does not exist.

Reproducible: Always

Steps to Reproduce:
1. Create a java project
2. Create 2 new classes within the project, leave the editors open
3. Restart eclipse
4. Delete the project (no need to tick the permanent deletion checkbox)
5. The exception will now be shown in the editor which had not been instantiated (ie the one "below" the one for the second class that you created)
