JOSM freezes every time I add a POI as a building. I can add 1-2 tags before it freezes. I can still add the POI and buildings separately and combine them.

[ian.malott@…]

What steps will reproduce the problem?

1. Add a building.
2. Add a POI tag to the building and use Shift+return to add another tag.

What is the expected result?

To be able to add a POI as a building without JOSM freezing.

What happens instead?

JOSM will freeze and you will be unable to do anything else without force quitting JOSM.

Please provide any additional information below. Attach a screenshot if possible.

This has happened a few times in different parts of the world. It always happens when I use Shift+return to add another tag to the building.

Looks like a deadlock. Next time it happens, please share a threaddump so we can analyze it.

[taylor.smock]

Just so you know, you can get a thread dump by running the following command (Linux/Mac): jps -l | grep "org.openstreetmap.josm.gui.MainApplication" | head -n1 | awk '{print $1}' | xargs jstack -l. I would recommend doing this a few times (say 10, once every 10 seconds or so) and putting the output in a file. You can do that by modifying the xargs jstack -l to be xargs jstack -l >> stacktrace.log.

For example, for i in {1..10}; do jps -l | grep "org.openstreetmap.josm.gui.MainApplication" | awk '{print $1}' | xargs jstack -l >> josm_stacktrace.log; echo ${i}; sleep 10; done.

Note: Don't have two versions of JOSM running at the same time when you run the command -- we might not get the "right" JOSM with that command.

EDIT: If you don't know where you are in the terminal, run pwd. Or (on Mac) run open ., or (on Linux), run gio open ..

I cannot do anything without the thread dump I asked. Please reopen if you manage to get one.

I see nothing wrong in the thread dump. No deadlock, and I can't reproduce this issue.
