JOSM freezes after showing popup for unsuccesfull search

[GerdP]

What steps will reproduce the problem?

1. Load some data
2. Search for an object that doesn't exist, e.g. highway=xyz
3. A popoup is shown that nothing was found
4. Sometimes this popup disappears when I press Enter or Esc, sometimes not. I decided to open a ticket

and while reproducing the problem JOSM decided to freeze.

What is the expected result?

Popup should disappear

What happens instead?

In this particular case JOSM no longer reacts. I cannot close the popup by pressing Enter or Esc or by clicking on the OK button. When I click somewere else I hear a Windows System Sound.
Pressing Alt+F4 also doesn't work.

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

Happened a few more times now. I have no idea why and I don't know much about GUI programming, so I can't help with a patch :-(

In 12839/josm:

fixed #15198 - JOSM freezes after showing popup for unsuccesfull search

[GerdP]

Looks good. No problems during the last two days.

[GerdP]

Sorry, happened again right now (with r12839).
If I got this right it happens when I do this:
1) Start unsuccesful search
2) Press Alt+Tab to switch to a different Window, e.g. Firefox, press some keys in this app
3) Press Alt+Tab again to switch back to JOSM
4) Press Esc to remove the popup
JOSM no longer reacts.

[bastiK]

Please add a thread dump for this freeze!

Cannot reproduce on my system (XUbuntu).

[GerdP]

new thread dump

[bastiK]

The line numbers in the thread dump do not match the source code. Could you please double check, that you are running version 12839 or later (and not a custom build)?

[GerdP]

Strange.
JOSM help says version 12839. I compiled it from svn and I don't see any modifications in the java sources.

I've just updated to 12879 and used ant clean dist to compile. I am not able to reproduce the problem with this version
while I was able to reproduce it this morning with the version that said 12839. Maybe I did not use ant clean to compile that buggy version.

[GerdP]

Tried a few more times, now it happened again with 12879.

[bastiK]

Replying to GerdP:

Maybe I did not use ant clean to compile that buggy version.

This seems like a plausible explanation, but apparently it makes no difference.

[Don-vip]

I can't reproduce it on Windows. Please update your version of Java and open a new ticket if reproduced.

[GerdP]

See #15375. I was able to reproduce it two times (with two tries)
