Hi,
we just installed the new 2022.03.0 version on our test server and we have a problem.
We use smart client and we just downloaded the jnlp.
Opening it we get this error:

JNLParseException[ Impossibile analizzare il file di avvio. Errore alla riga 0.]

And this is the XML content:

<?xml version="1.0" encoding="utf-8"?> Servoy Client Servoy Database client system.property.apple.laf.useScreenMenuBar:true

How should we fix it?

hard to say, somewhere in all those plugins (jnlp files) there is some kind of error

What happens if you test it with a basic install without any 3rd party plugins.

I had the same error. But also the following error in Servoy log:

com.sun.org.apache.xml.internal.serializer.utils.WrappedRuntimeException: Could not load the propery file 'output_xml.properties' for output method 'xml' (check CLASSPATH)
...

Turned out that it was due to a Java update on the server (and not restarting Tomcat).
Restarting Tomcat and clearing the java cache on the client solved the issue.

Hope this helps.
