Description

I admit it is somewhat a corner case, but – I have a TopComponent whose getPersistenceType returns PERSISTENCE_NEVER and so a corresponding config file is never created on config fs. If the user closes the document group which contains such an editor, the core throws a NPE:

java.lang.NullPointerException
