We have fixed the jar cache key to use Url string instead of the Url. We are hoping that this would fix the problem. we are planning to make a release this week. You can try the new release.

Planned for this week unless there are some issues.

PS: we are using log4j2.17.1 which I noticed was flagged in another thread here as problematic but I am not sure if for the same reason

Hi, Thanks for registering with the forum. There is already an issue : https://github.com/karakun/OpenWebStart/issues/530 What happens if you disable the console using the itw-settings app? Unfortunately we have no plans and resources to fix the memory leak due to console at present. Could you consi...

Hi The order in which the resources are specified matters. If you switch the order of x86 and x86_64 as follows it will pick up vmargs for x86_64: <resources arch="x86_64"> <java version="17*" vendor="Eclipse Adoptium" java-vm-args="--add-exports=java.desktop/sun.s...

I am able to reproduce the problem on Intel Mac with the following Jnlp file: ... <resources arch="x86"> <java version="17*" vendor="Eclipse Adoptium" initial-heap-size="511m" max-heap-size="1023m" /> <jar href="generated-jars/jvm_args.jar"...

This has been fixed https://github.com/AdoptOpenJDK/IcedTea-Web/pull/925 and will be part of the next release.

We have created an issue and will try to fix in the upcoming release. Probable fix could be for OWS/ITW to ignore loading classes from Jar Indexes for JDK >= 21 https://bugs.openjdk.org/browse/JDK-8302819 " https://www.oracle.com/java/technologies/javase/21-relnote-issues.html#NewFeature core-l...

I could reproduce.

With Java 11,17,18,19,20: App runs even if sun.misc.JarIndex not found, jdk.internal.util.jar.JarIndex is found and used.

With Java 21 jdk.internal.util.jar.JarIndex is not found.

I will try to reproduce it and revert.

Ok Thanks for the sample. I will try to reproduce it.

> As it is a GET call, the application create the <jar> with the sessionId (found in the request done to build the jnlp file) I could reproduce the issue by generating a jar on the fly. I will investigate your issue and check if caching can be improved. However, I would still request that you consid...

> jar href='{apiUrl}/{jarName}?JSESSIONID=rsoklofhej136qcq0unu2c7smf It seems you have edited the logs as the Jnlp file has some place holders. I would like to see the Jnlp file that is actually processed by OWS. In your Jnlp the url of jar file has been rewritten to include the session id. Is the J...

Please attach the stage 1 and stage 2 log files.

Which version of OpenWebStart are you using? Can you please send the log file?

I tried with the following jnlp file and it works ok om Mac OS X with arch x86_64: ?xml version="1.0" encoding="utf-8"?> <jnlp spec="1.0+" codebase="http://192.168.2.104:8080/jnlp"> <information> <title>JVM Args</title> <vendor>Karakun AG</vendor> <offline-all...

Hi

Would you be interested in testing the fix with your application?

Thanks

I can reproduce the issue. When the resource jars are directly present in jnlp, the resource is found only once. However, when the resources jars are in the extension jnlp, the resource is found twice. I will investigate and fix it. Thanks for pointing reporting this bug.

Thanks for the sample. I will try and come back to you.
