Gui: NPE after renaming model file (*.jm)

[vsgfe]

Description of the Issue

I opened a model file and saved it, then closed Jailer. I noticed an error in the file name so I renamed the file on the file system. I started Jailer again, it tried to load the recent file list and could not find the file. An error message with stack trace appeared

Steps to Reproduce the Issue

1. open a jm-file
2. save it
3. close Jailer
4. rename jm-file
5. start Jailer again

Expected Behavior

remove missing files from the recent file list and continue to start Jailer.

Actual Behavior

NPE:
