JMapViewer - tiles stopped working

[tjeziorowski@…]

The map tiles in JMapViewer component stopped working today. All I see ar red X marks. I'm getting reports from other users that they also have this issue.

Confirmed, we get HTTP 429 (Too Many Requests) and jmapviewer retries in loop, worsening the problem:

I see this problem only in the imagery preferences (see ticket:16301#comment:70). The download window and the mapview work fine for me. See console log below, the first are from the preferences and the last from the mapview. The first are rejected while the last work fine despite both use the same URL pattern https://{switch:a,b,c}.tile.openstreetmap.org/{zoom}/{x}/{y}.png

MapView doesn't use JMapViewer and has its own (and much better) tile loading mechanism.

[Don-vip]

In 15145/josm:

see #17772 - make sure all JMapViewer instances in JOSM behave the same

[Don-vip]

@Klumbumbus please test in JOSM imagery preferences with r14145 it should work.

[Klumbumbus]

Yes, works fine.

[Don-vip]

Fixed in [o35016:35022].

Thanks, it works great now :)
