Hello all,
After some years not using NetBeans RCP (only de IDE), I’ve tried to follow the
"NetBeans Platform Quick Start Using Maven” using NetBeans 16 with Java 19.
When I try to "Build with Dependencies” the app the following error appears at
compilation time:
Running es.intellectusetanima.mavenplatformwordapp.ApplicationTest

SEVERE: No way to find original stream handler for jar protocol

If I try to run the app, I have the previous error plus the following:

access class sun.awt.AppContext (in module java.desktop) because module
java.desktop does not export sun.awt to unnamed module @5cc73178

Anyway, the application starts.
The same happens using the alternative way of building an RCP app (i.e. using
Ant-based development, as in NetBeans Platform Quick Start for NetBeans
Platform).
Now, how can I get rid of these errors? Do I need a moodule-info.java file? If
yes, where? Otherwise?
