JOSM froze and unexpected Exception error is the only thing available

[beth_gis@…]

What steps will reproduce the problem?

1. I was editing an OSM from ​http://tasks.hotosm.org/project/1009#task/83
2. I was looking through the imagery available, and tried loading the last file I worked on
3. The new file was gone, the last file appeared, then everything froze

What is the expected result?

I expected I could go back to the ​http://tasks.hotosm.org/project/1009#task/83

What happens instead?

all of JOSM froze

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

Also, I just noticed that I have java 32 bit installed on my 64 bit windows 7 laptop. I might have chosen a 64 bit JOSM if I got a choice when I installed JOSM (2 days ago). I haven't had this problem before.

JOSM runs in whatever mode that your Java is. So, if you install the x64 Java, JOSM will run in x64 too.

Create a shortcut on your Desktop with this information:

Target: "C:\Program Files\Java\jre7\bin\java.exe" -Xmx2048M -jar josm-tested.jar
Start in: "C:\Program Files (x86)\JOSM"

That's how to get JOSM to run and have more than enough memory to run it properly in x64 mode once you have x64 Java installed on your computer.

NOTE: You need to change the 'target' code to adjust to wherever you have Java installed. So, if you have Java8 installed, change the 'jre7' part to 'jre8'.

Looks like a very old and rare problem of JOSM, difficult to reproduce and never fixed: #5808, #6444, #6555
