JOSM throws exception after loading a TMS map and zoom(ing)

[Nakaner]

What steps will reproduce the problem?

1. Start JOSM
2. Add a background map layer (e.g. Bing or Mapnik).
3. Zoom out and you will get the exception listed below.

It does not matter if a data layer is loaded and if the data is from OSM API or loaded via remote control from Overpass (Turbo).

I have not tested WMS layers.

What is the expected result?

No exception should happen.

What happens instead?

JOSM throws exception but imagery is still loaded. The exception is thrown multiple times at once (maybe one per tile or per zoom level?).

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