Cannot close an application launched with OpenWebStart

[filippoAdb]

I'm new with Open Web Start, I'm evaluating it as an alternative to Jre 1.8 for JNLP applications such as this one:https://jws.agenziaentrate.it/jws/dichi ... 77024.jnlp
I installed OpenJDK Runtime Environment Microsoft-10377968 (build 21.0.5+11-LTS) and OpenWebStart 1.11.1, then I put the link above in the browser.
After the application jar files were downloaded the working window opened, apparently it was running well, unfortunately it cannot be closed using the menu or the cross icon.
It correctly works using Jre 1.8 and its web start.
Besides on first run that application performs some initial configuration and creates a shortcut. Using OpenWebStart it always behaves as it was the first run,
it asks again one time configuration choices, which clearly is not correct.
If there is no easy way to fix this problems I have to abandon OpenWebStart

Thanks
Filippo

Once OWS does not control the behavior of an application in any way. OWS just launches a jnlp application with the JVM that best matches that specified in the Jnlp file. You say that with Java 21 the application is starting but after that you are not able to close the window of the application.

Does the application code needs to be ported to newer versions of Java? Do you need to specify additional JVM args in the jnlp file to make it run with JREs > 1.8?

Please check OWS logs in case your application has logged some messages.

I enabled log on file. When I try to close the application(Esci command) there are lots of exception, but I have no idea how to deal with them.
The root cause seems to be:

Code: Select all

java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.Comparator 
java.util.TreeMap.comparator accessible: module java.base does not "opens java.util" to unnamed module @af975d7

Any help will be appreciated

Here is an extract from the log:

It seems that to work with Java 21 your application needs to add some module related JVM args in the Jnlp file. Please find out the module dependencies required by your application and add the required modules related JVM args.
