Ok, I think I solved it. At least locally I'm able to run our project
now. Although the release version also probably needs these flags to
somewhere (*.conf). But the local can be run by adding:
\nbproject\project.properties
run.args.extra=-J--add-opens=java.base/java.net=ALL-UNNAMED
-J--add-exports=java.desktop/sun.awt=ALL-UNNAMED
-J--add-opens=java.desktop/javax.swing.text=ALL-UNNAMED
-J--add-opens=java.desktop/javax.swing=ALL-UNNAMED
-J--add-opens=java.prefs/java.util.prefs=ALL-UNNAMED
-J--add-opens=java.base/java.security=ALL-UNNAMED
-J--add-exports=java.base/sun.reflect.annotation=ALL-UNNAMED
There is probably more of these --add-opens / exports needed depending
on one's project but this seemed to suffice for us.

Hi!
We have a Netbeans Platform project with Ant build. Currently it is
hooked up with Netbeans 16 and Java 11. Everything is running
smoothly. However, we would like to transition to Java 17. Running the
project with JDK 17 stops to a problem immediately. Is it even
possible to use JDK 17 with Netbeans platform project?
The error:
SEVERE: No way to find original stream handler for jar protocol
