CPU spins at max when Find Dialog opened (no repro, memory dump available)

[watmildon]

What steps will reproduce the problem?

1. Downloaded 39.8765464;-86.2722015;39.9318539;-86.1558151 with this overpass:

   [out:json][timeout:25];
   (  
     way[highway]({{bbox}});
   );
   // print results
   out body;
   >;
   out skel qt;
   

2. searched for this ("tiger:reviewed" AND highway AND -name_1 AND -"tiger:name_base_1")
3. moved around the area looking at results
4. Opened search again

What is the expected result?

Search box opens and is operational

What happens instead?

CPU spun up to the max for one core for an indeterminate time.

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

I hit a weird condition where opening the JOSM search box caused it to spike the cpu continuously and the search box was unresponsive to keyboard and mouse input for many minutes with no sign of stopping. I am not able to reproduce this issue but did collect a memory dump if that's interesting or useful.

It would be appreciated if you could upload the memory dump. I'm not hopeful -- profiling would probably have been a better option, since it would have shown which methods were taking up the CPU time/memory allocations (depending upon settings). If you have a JDK installed, look for Java Flight Recorder if this happens again.

If we are lucky the memory dump will show something very wrong, but things that are not the problem are likely to overwhelm the problem.

[watmildon]

I'm happy to send you a link to the dump via slack. Not sure I want a full memory dump available broadly (has my tokens, ip etc etc). I will make sure to have Java Flight Recorder on hand in case the issue reappears.

Replying to watmildon:

via slack

Is it an official communication channel? Because I don't see modern apps in the contact section, although interested in one where I can get answers without creating a ticket.

[taylor.smock]

I'm on the following networks:

• Matrix
• Slack
  • OSMUS
  • HOTOSM (bridged in via Matrix)
• OFTC IRC (#josm and #osm, bridged in from Matrix)
• OSM World Discord (bridged in from Matrix)

My handle on most of the networks is some derivative of vorpalblade for the most part. You should see the display name as Taylor Smock.

EDIT: To clarify, none of them except for #josm are official communication channels.
