JOSM causes infinite unexpected exceptions

[kevinsteinhardt@…]

The application runs into an infinite call of unexpected exceptions when attempting to download an area around a location found by using Nominatim — 'Download from OSM', 'Areas around places' tab. On selection of a found locale, the application throws up a (seemingly) infinite number of "unexpected exception" dialogs. JOSM build 3208 running on Ubuntu 10.04; Java version unknown.

You must be more specific. What search did you use? What errors does JOSM throw. How to reproduce?

It's infrequently on any download. Said problem has (even though there must be a better word that) developed since reportation. Infrequently, on any download of data from OSM — whether that's using the slippy map, bounding box spec, etc. — the application throws up blank error dialogs, only bearing the title "Unexpected exception". I've tried a few times, each time quitting and restarting the application, to force the error to come back, so I can at least a screenshot; I have had no errors since. The application has not been updated in any way. And, no: I've never been any good a filing bug reports.

It's a start. Can you add the console output?

[kevinsteinhardt@…]

And how would one go about locating that? (Linux noob; Mac user, primarily)

[bastiK]

Open a console window and type

java -jar FOLDER/josm-latest.jar

(see also http://josm.openstreetmap.de/wiki/InstallNotes)

Please ask if you have further questions.

Terminal output re: bug in question

[kevinsteinhardt@…]

Att. terminaloutput.txt; was actually quite difficult to save this, as the new dialog boxes disturb focus and selecting a menu item is rather difficult. I also have a screenshot, but the 'Take screenshot' window is kind of in the way; the dialogs are empty with the window title "Unexpected exception".

[bastiK]

OK, the output you have posted is just the endless loop. We also need the first part, which usually shows the cause of the problem.

I'm fully aware of that fact; the way I'm saving the output only exports the last part. I guess I could log the session, but it took a few dozen instances to get the thing to crash.

[bastiK]

You can try

java -jar FOLDER/josm-latest.jar >log.txt 2>&1

Extended output from the Terminal

Seems we have a situation, where the bug report handler again causes a bug. Would be nice if we could reproduce that.

Fixed in r3478.
