[anonymous]

What steps will reproduce the problem?

1. start OSM
2. read first line above the version news.

What is the expected result?

nothing

What happens instead?

There is an announcement, im the first line that my java version soon will not be supported anymore. I should update to version 11 or better...
But my java version 8.341 seems to be the newest version available according to java update function...
So I should ot get any message about too old java version.

Oracle does not provide a higher java version but other do. You might want to take a look at our windows installer which includes a higher java version, see Download.

Please, always use a 64-bit java version on a 64-bit operating system. This by the way will allocate more memory for JOSM without manual changes. So you might want to uninstall java 8 completely prior to installing the windows installer.

Now I did look up the favoured "Azul" platform, downloaded and unzipped 64Bit version but did not manage to install. There is a *.msi installer mentioned in their help text but not available in the download. I am no IT professional but not so dumb im this field too... so many other users might have the same problem.

• using Oracles versions and update program will be in wide spread use (many people will Java still connect with Oracle in their mind, so using this, or just because they only updated again and again)
• not beeing able to install the prefered other Java versions without precise instruction and/or automatic installer will affect others too. in tehe comment on JOSM Start page there is not even a comment on those preferred versions.

It is simply no topic I want to invest much time into updates where I get no clear instructions. Would rather invest it in mapping...
If you change to Java versions no longer supported by the Oracle java versions, there should be Installation instructions suitable for people who just want to have JOSM work. Of the sofware provider Azul does not, it might be yor task to give this information. Please consider teh knowledge leveel of end users....

btw, i always use the windows installer. But if you have the recent JOSM Version installed, the installer starts and then finishes without any message (would expect at least some message "you have the latest version installed), so I have no access to the usual download page and possible links there)

For the missing message, see #22053.
Sorry, I was not aware that you had already used the installer. Sadly, the installer does not update the java version if java 8 is installed. You need to uninstall JOSM plus probably java 8 first and then install JOSM with the up-to-date installer which should provide java 17+, see #21307.
You might want to backup your preferences, just in case, see Help/Preferences and check Help/Action/About for the locations.
That said, I do not have a windows system and can only repeat what others wrote.

Thanks for qick answering,

After some new search I managed to find a msi installer at ​https://www.azul.com/downloads/?package=jdk#download-openjdk and tried it out.
I did not deinstall Oracles 8 version before, it is aorking fine with it still installed, because you are prompted on te next start of JOSM which program to use...
But I have still some problems this his ticket:

1. the message at JOSM start page still indicates wrongly, FURTHER Versions of JOSM migth not work below Java 11. Instead even THIS recent version of JOSM absolutely WILL not work without version 11.
2. Then you should add below this information the above mentioned download link and advice to download and execute the 64Bit Windows *.msi installer als a Windows User (as a mapper you do normally not even read the recommendations to use this rather exotic new versions, and if you look up for "Java 11 download" at google you get not much helpful stuff.
3. the overall philosophy of such updates sould be re-evaluated. The target group of your communication is mainly mappers with very different levels of computing knowledge, from experts to people who can start and use JOSM HMI but not so much more. So If you do a change which will render JOSM de facto useless until some things are done:

I would expect an announcement at least one version before the problem will occure.
I would exect to have a description page prominentely linked with the update announcement with a step-for step instruction for the non-expert group. Would spare alot of work because I will not be the only one with problems. It is not in Your interest to be bombarded with tickets because of missing instruction.

4. I am used to support tickets are not closed until...
   • a clear instruction about how the problem can be solved by the normal user (bo computing expert) is given
   • the problem is solved for the user (indicated e.g. by users answer) or
   • after some time, if you can assume the user does not track the ticket anymore. Posting a commentary and closing the ticket might be less work but is bad style "customer service".

tx for considering

Good to know that you managed the upgrade.
Did you try the installer after de-installing JOSM and Java?

No worry, I mostly reply on comments of tickets which I have closed.
You did not ask for help but report a defect which is invalid in several cases.
I have changed the ticket to ask for a link to a wiki help page. The link needs to be integrated into the macro. Do you recommend any existing wiki page (which could be extended)?

Anyway, you are already welcome to update or extend the wiki.

It should still be working, as we are still targeting Java 8 for our builds. I just checked josm-tested.jar and all the classes in it are compiled for Java 8 or earlier. If you have conflicting information, please open a ticket with the problematic jar file.

I would expect an announcement at least one version before the problem will occure.

The warning has been there for months (see wiki:StartupPageSource?action=diff&version=3048 ). We do need better instructions, but we haven't made the move yet (see #17858).

GerdP has also encountered this problem. I don't have a windows machine, so I cannot troubleshoot it. I've got a guess for what will fix the problem (see #22053), but it is just that, a guess. I probably ought to apply the guess to a git branch and have GitHub actions build an installer for testing.

After updating to the new java 11 version i do not get the warning anymore and all things are running fine. So I cannot provide any things concerning the topic which I can reproduce myself at this time anymore. All I can say i had the "newest" Oracle 8... version and got the warning and JOSM did not load more than 1 background layer at once. Then I installed the recommended version 11 via msi installer. After that it worked again as usual. Then came a new start page request to update JOSM and I did, since then the version warning did not re-appear. I did not find any information about this new updates content at start page as usual...very strange indeed.
But please put rather something at the start page with some mapper-friendly instructions how to upgrade to the 11 version. Might make is much simple to other users. And prevents the above problem from the beginning. Have the people simply do this update step by step once instead of looking fo probable cause....I do not know if you can see, which versions users have, certainly via uploaded bug reports. I would think, most have the 8.xx versions.No real problem to change over, but needs to be organized and communicated to mappers at a quite simple step-by step advice....

This sounds like you were running the x32 version of Java 8 (which makes sense given your status report). The Java x32 version (by default) gives us relatively low memory allocations (~256 MB), and JOSM works best with more than that, especially as users add more background layers. We do recommend in wiki:Download#Java that users use x64 bit versions of Java.

I've updated the link on the start page, specifically java.com -> azul.com ( wiki:WikiStart?action=diff&version=334 ).
