JOSM does not see the new version of Java 17

[anonymous]

I have Java 17 installed, but josm.jnlp does not see it and tries to start with the old Java 8 (I had to leave Java 8 and Java 17 together). But josm-tested.jar works fine for me in Java 17

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

You should change that. Maybe the path to the old JRE is specified in a desktop icon? Or the new one should be configured?

I downloaded a new one and it immediately tries to start through Java 8, how can I tell it to start from Java 17?

Does this help? https://josm.openstreetmap.de/wiki/Download#Webstart

I guess this has to be changed in the .jnlp

java version="1.8+"

Does it work if you manually change it to java version="11+" with a text editor?

I changed it, but in the file properties in the “Object” field there is an entry:
"C:\Program Files\Java\jre-1.8\bin\javaws.exe" -localfile -J-Djnlp.application.href=https://josm.openstreetmap.de/download/josm.jnlp "C:\Users\Users\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\56\1ee8cfb8-5d66748b"

If I change it to a folder with Java 17, it won’t open, how should I change it?

I followed the instructions in https://josm.openstreetmap.de/wiki/Download#Webstart and I have now an icon with josm.jnlp on my Desktop which starts JOSM 19017 in a Java 21 JRE. I guess I can change the JRE in the configuration dialog for OpenWebStart.

I'm betting you still have Oracle Java 8 installed. For the JNLP, we recommend ​OpenWebStart.

You may have to fiddle with the Open with right-click option if you keep Oracle Java 8 installed.

Do you also have OpenWebStart installed as recommended?

Is it possible to run josm.jnlp without OpenWebStart? So many different additional programs for one josm - it's stupid. I installed Java 17, why is this not enough?

It is. You already mentioned that you can start JOSM on the command line. My understanding was that you prefer to use the *.jnlp file to start JOSM, and we recommand to use OpenWebStart for this.

You say that josm.jnlp is an already tested version, josm-tested.jar is not. How to work with the stable version without OpenWebStart?

[GerdP]

r19017 is the curent tested version of JOSM, the corresponding jar file is named josm-tested.jar.
In a few weeks there will be a newer tested version, it will also be named josm-tested.jar, but that jar file will be different.

The advantage of the *.jnlp file with OpenWebStart is that it will automatically download the newest tested version of JOSM. I think it will also download a newer java version if wanted.
Hope it is clear now?
