[Wildwater]

What steps will reproduce the problem?

1. Start JOSM, start editor
2. run validation
3. Click on rasterfiles ICON, contrast/brightness is preloaded in window, click add
4. Attempt to move contrast slider to increase contrast

What is the expected result?

Contrast increases

What happens instead?

The "You have encountered a bug in JOSM" window appears. By Ignoring the error, the contrast slider is present, available and functions.

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