Try disabling assistive_technologies=org.GNOME.Accessibility.AtkWrapper in /etc/java-7-openjdk/accessibility.properties. See also: ​openjdk-7-jre-headless: Please re-disable atk bridge

This line was already disabled in /etc/java-7-openjdk/accessibility.properties

Tested the latest stable josm version (9979). The application starts, but the same error appears when trying to open some osm data.

[kalxas]

It appears to be network related, josm does not work even on 9.5beta1 (josm was confirmed to work on that build a month ago)

[kalxas]

This seems to be a problem with the network setup of my KVM testing environment. JOSM fails to contact the OSM servers on startup and crashes.

After downloading the latest iso and testing under VirtualBox, JOSM does not have any problem.

built a clean test environment under VirtualBox; cannot reproduce error.
