Unable to import OSM file

[philipz]

What steps will reproduce the problem?

1. Open JOSM
2. Open a OSM file that used to work fine in version 7000

What is the expected result?

To load the osm file

What happens instead?

I get an error message like "Could not read file 'xxx.osm'. Error is: Unsupported version: 0.5 (at line 2, column 47). 91 bytes have been read"

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

Closed as duplicate of #9975.
API 0.5 support has been disabled a while ago. You can try to manually set the version to 0.6 directly in the osm file.
