Auto Tools

[jhfi]

What steps will reproduce the problem?

1. Install Auto Tools for the Knife Tool ​https://wiki.openstreetmap.org/wiki/JOSM/Plugins/Knife-tool
2. Download an area of the map
3. Load a layer such as Bing Aerial Imagery
4. Use the Knife tool to split a way
5. Delete the layer without saving
6. Press ⌘ Shift ↓ (On a Mac - unsure of whether this bug affects Windows/Linux machines)
7. An exception shows and will show for every further keypress until JOSM is restarted.

What is the expected result?

For the "Download from OSM" window to be displayed.

What happens instead?

The "Download from OSM" window is not shown, and an exception is shown on screen for every further keypress until JOSM restarts.

Please provide any additional information below. Attach a screenshot if possible.
