1) Select a method in a type, i.e. all viewers are populated, editor is visible
2) Deactivate linking between active editor and navigator in workbench 
preferences
3) Deactivate auto build
3) Prespective>Show View>Navigator
4) Pin Navigator
5) Select the folder containing the file of the previously selected method
6) Context Menu>Delete
-> Types list is not flushed
7) click around in Types View, open Context Menu on an item, double click on 
items
-> while doing so I ended up with the NPE
