Shortening a connector to 0 length causes NullPointerException

[JohnCC330]

At least in State Machine, shortening a connector arrow to zero length (in my case accidentally):

• produces: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException on the terminal
• disables the drawing area - no editing can be done, or new elements 'dropped'
• leaves pink/orange square in the drawing area
• The main menu 'Help' drops down, but no elements can be activated.

This is on Linux, UMLet 15.0.0

Hi thanks for the report, unfortunately it is a new bug in v15 Umlet Standalone+Eclipse Plugin which was fixed in #679

If you cannot wait until we release v15.1, you can download the current build which already contains the fix at https://github.com/umlet/umlet/actions/runs/2587912447
