Hi all,

I have been running the following command on Windows 7 for the last year to run the most up-to-date tested JOSM jarfile:

java.exe -jar -Xmx512M josm-tested.jar

For the last few days (from about Jan 30th 2012) i have been receiving the following exception:

'Invalid or corrupt jarfile josm-tested.jar'

I am using josm-tested version 4878

Any ideas?

I have downloaded the latest jarfiles

I am running the latest JRE: Version 6 Update 30

Are you sure that you've correctly downloaded the JAR file?

First, what is the size of the file? Mine is 7Mo.

Ok, so something is wrong with your download. Which web browser are you still using? Try another one: firefox, IE, chrome, …

I was using a python script which checks the latest online version before opening JOSM & downloads a new one if the version number has increased.

It has worked successfully for at least a year, i don't know why it is now not working. I'll try to fix the python script or just download manually in the future.

Thanks for your help

Have you tried downloading the latest jar file again, perhaps after deleting the copy you downloaded already? I'm using 4878 on Windows 7 without any problems (though give it a bit more memory -Xmx1500m).

Having said that I only seem to be on update 22, so will update and check again.

Edit: I've updated to update 30 and still all is OK.

What version did you upgrade from? A few stable releases ago I had problems starting JOSM (I don't think it was a corrupt jar message though) and had to remove my settings files and start configuring it from scratch again. I renamed the folder

C:\Users\Ed\AppData\Roaming\JOSM

to

C:\Users\Ed\AppData\Roaming\JOSM-backup

just to perform the test

I have downloaded the latest jarfiles a couple of times, i am thinking this might be a Java issue as i have gone back in the josm archives and downloaded previous versions that should have worked from last year and i am still getting the same problem. I have also removed my settings files which has not changed anything

Have you tried then uninstalling Java and redownloading it? (As I did to update from 22 to 30).

I've uninstalled & reinstalled java and still have the same problem. It must be a problem with my system, i will try to run some other executable jars.
