Layer rendering improperly in JOSM but works everywhere else

[anonymous]

For some reason layer "Geoportal 2: High Resolution Orthophotomap (aerial image)" works everywhere (Example) but in JOSM.

Link to layer: ​https://mapy.geoportal.gov.pl/wss/service/PZGIK/ORTO/WMS/HighResolution

WMS is not working because entry doesn't contain

 <custom-http-header header-name="User-Agent" header-value="Mozilla/5.0 (JOSM)" />

As other entries for Geoportal. For some reason, Java string in User-Agent is banned at Geoportal.

Try zooming in on any working coordinates you will get this:

Works by me right now. Though I've also noticed this problem for some period of time. Cleared the cache, and then problem disappeared. Not sure, if this was something on the server side or on our.

the bug is still present after deleting all the files in ~/AppData/Local/JOSM/cache

To me honest for me even the "GetCapabilities" link (​https://mapy.geoportal.gov.pl/wss/service/PZGIK/ORTO/WMS/HighResolution?service=WMS&request=GetCapabilities&version=1.3.0) dose not work in JOSM. When trying to get the available layers I get the error:

javax.xml.stream.XMLStreamException: PraseError at [row,col]:[1,1]
Message: Premature end of file

[wiktorn]

In 17502/josm:

Check current tile projection when querying WMS server.

Add same logic as in WMSEndpointTileSource to check, whether coordinates needs
to be switched or not. Before this change, switch was calculated only when
adding the layer, so changing map projection was ignored.

Also it was using JOSM map projection settings instead of the projection that
was chosen to query the server and this could result in replaced X and Y
coordinates.

Closes: #20509

This is usual message if you haven't customized User-Agent in case of this server. Turn on Expert mode (e.g. in preferences windows, bottom left checkbox), then start adding WMS, but first set in the table with "custom HTTP headers" header name and value as I mentioned in comment:1

This WMS doesn't work for me either in JOSM with default settings but works fine in QGIS. As far as I can tell JOSM automatically adds custom user agent like "Mozilla/5.0 JOSM" or something so that shouldn't be an issue.
JOSM version 17428

I tested it with projection 3857 (which this WMS doesn't support and is the default projection for JOSM) and projection 2180 (supported by wms).
With 2180 it works fine, with 3857 tiles are completely wrong.
Changing projection after adding WMS layer doesn't work. Only if I change the projection first then load WMS layer.

It seems like a bug with JOSM reprojection algorithm.

If this is the same problem that you've reported earlier, this was fixed in version 17502. Please test it with version 17502 or later.

Your description matches exactly the bug that was fixed in version 17502.
