Package: josm
Version: 0.0.svn18969+dfsg-1
Severity: normal
X-Debbugs-Cc: a.t.chadw...@gmail.com
Dear Maintainer,
When JOSM is instructed to download Bing background satellite and aerial
imagery, it hangs the first time JOSM is launched on a day of map editing.
It seems to be a key caching issue. If JOSM is then killed, and
subsequently launched again, it downloads the Bing imagery just fine.
If enough time then elapses without launching JOSM, the situation repeats.
For me this is usually about a day, but the timeframe is probably a lot
shorter.
I would expect Bing background imagery to be downloaded fine every time,
without causing JOSM to hang.
## Minimal Steps to Reproduce
The hang will happen in all ordinary usage when Bing imagry is used, but in
order to rule out config files and settings, you can run JOSM as
$ JAVA_OPTS="-Djosm.home=/tmp/josmhome.$$" josm --skip-plugins --debug
This prevents it from loading your personal config file or any downloaded
plugins. As soon as the main interface loads, add a Bing layer using
Imagery → Bing aerial imagery
If this is the *first* time the josm.home location is being used (i.e. it
didn’t exist before), JOSM will then hang with the final debug messages
shown immediately below. JOSM then hangs and has to be killed with ^C or
using xkill.

JOSM does not hang, and goes on to print messages like
