JOSM cannot open file if it contains the char & in the url/name

[baditaflorin]

When i try to open this file in JOSM, i get this error, that it`s cryptic and does not tell nothing about what the real error is.

This is happening because of the & in the url.

If i delete the & i will be able to load the file.
But this not solve the problem, this is a valid url.
Also, the same problem appears when adding a name that contains the char &

For the file fake_bbox_area14.osm, it will fail to load because of the & char.

If you try and download the data, it will work.
