Entered minor changes, JOSM appeared to hang

Posted by Richard Hufford on 26 October 2014 in English (English)

I entered a few corrections near Geronimo, Arizona, because I drove through the intersection of Geronimo Lane and Black Lane and it was a little bit different from what the map showed. When I closed JOSM, selecting the Perform Changes button, JOSM appeared to hang with the message "Preparing layer xxx for upload." showing on the dialog window. It appears that the changes were successfully uploaded. I will check in a day or two to see that my changes are intact. Note that I updated my Java version today (Oct 26, 2014) before running JOSM.

I should mention that I'm using Windows 7, 64-bit

Location: Geronimo Lane, Geronimo, Graham County, Arizona, United States of America

The main OSM server(s) has been planned for maintenance and quick downtime the 26th. See the announcement here :

Your josm upload issue is probably related.

I made some changes today (30 November 2014) and had the same result. The message shown by JOSM is "Preparing layer 'Data Layer 1' for upload...." and JOSM appears to have hanged. However, looking at my profile on, it appears that the changeset has been saved.

Note: The hang might only happen when I save the changes while exiting JOSM. I just made another change and clicked the Upload button, and everything worked perfectly. Then, I exited the program and had no problem.
