1. Create a simple Java project with two trivial classes, Class1
    and Class2.

 2. Open a Java editor on each class, ensuring that **Class2's**
    editor totally obscures **Class1's** (i.e., don't tile the
    editors).

 3. Shut down Eclipse and restart it. Things should look pretty
    much the same as before.

 4. Choose "New Window" from the Window menu.

 5. In the new window, delete Class1 using the Package Explorer.

 6. Go to the original window. You'll notice the editor for Class1
    is still there. Click on its tab. Kablooie.

Obscured editors aren't instantiated on startup---only when they're
revealed. The error comes from FileEditorInputFactory when it tries
to reload the editor's memento information: the memento's path
points to the now-deleted resource.
