JOSM is changing the IDs

Description (last modified by simon04)

If you open a osm file, change nothing, and save it back, all/many IDs are changed.
I don't understand this behavior and if it's possible to change it. I don't see any other option …

Since the negative ID might already be in use in an other layer, JOSM replaces any ID <0 with a freshly generated one, see org.openstreetmap.josm.data.osm.OsmPrimitive#OsmPrimitive(long, boolean)

Consider:

  1. Start JOSM, create node, save as foo.osm (the node has ID -1), close JOSM
  2. Start JOSM, create node, save as bar.osm (the node has ID -1), close JOSM
  3. Open foo.osm and bar.osm
