This error happens when ITW is unable to download the resources. Could you please attach the log files for further debugging this. Thanks

I'm running into a same/similars issue from time to time (using OWS 1.3.1). Sometimes launching the app works, sometimes this or a similar error shows up. It seems to happen more often when I'm trying to launch the application multiple times. It could be a race condition on the download / cache. Maybe it's a problem with download speed dropping below a certain threshold (or 0 for short bursts?).

I've not yet have enough time to further investigate and I don't know when I will be able to. Just wanted to give a heads up, just in case it could help.

There are some Exceptions in terms of using the cache to be found: java.io.FileNotFoundException: C:\Users\xxxxx.cache\icedtea-web\cache\3\236\slf4j-api.jnlp (Das System kann die angegebene Datei nicht finden)

I can also see some logs that I dont' understand. The cache files seem to be deleted? Why does this happen?
This could be the reason (one application starting and trying to use the jar, other application deleting from cache?)

can you provide the log files? The stack trace is not helpful for us to solve this problem.

I've launched the application multiple times. Launching it once seems to work. Launching it twice at the same time seems to lead to problems.

@jastax
Thank you for the logs. I found the cause of your problem. A fix is here #728
Unfortunately it is a different one from the original reporter.

The next release is currently planned for April 2021.

@ulooky if you still need help on this issue, we would need log files from your case.

Hi @sclassen that's great, thank you.

I'm wondering about why the cache is even deleted though?

Is there a way to speed up the release? We'd like to use OWS 1.3.x in production starting in Q1/21.

We do offer different support options.
Details can be found on the official homepage: https://openwebstart.com/support/
There is also the possibility to have a customized splash screen.

For the free/community version there is only the half year release schedule.

I will take a second look at the cache deletion over the weekend

Just one question:
Have you set a limit to the cache size?
You can see the current settings in the settings UI on the "cache" tab.

I'm sorry, I'll only have access to the windows computer in January. I don't think the cache limit is set / that low though. I'll check it next month. My team lead has already requested support options pricing.

We have booked a support option now (LVM). I'd like to test whether the fix solves the problems - are you going to release it soon? :)

(We are using OWS, so the fixed Version would need to be applied there too)

We will do a release today. It will be available tomorrow and contains the fix for your issue.
Also we added more logging for the cache cleanup which will help debug the reason why in your setup the application is removed from the cache.

@sclassen That's great, thanks!

Can you please open a new issue for the cache cleanup if you can still reproduce the behavior with 1.3.2
Thanks
