In Open dialog, remove trailing space or get error

[anonymous]

[[Image(Hello,

There's a small bug when reading eg. a GPX file: If the string contains a trailing space, JOSM triggers an error.

If you don't know, it can take a while to understand what the problem is.

Well, that's by design. JOSM loads a set of different file formats which are all very similar and thus we rely on the extension to provide the filetype. There is no deep file inspection to determine the type based on the contents. So unknown extensions wont load and ".gpx " is an unknown extension.

The problem also occurs when you try such a name as a source for external validator rules.
Wouldn't it be easy and much better to try again with trailing blanks removed?
I've encountered this problem several times because I often have file names with trailing blanks in the clipboard.

Blanks in filenames are perfectly valid. We only strip blanks in places where they aren't valid.

Sure, nobody talks about removing blanks in the middle. I also don't suggest to remove the trailing blanks before trying to open the file. I just suggest to try again with removed trailing spaces if the given file name doesn't exist.
