I have downloaded the source code of Kettle 4.1.0 and I'm trying to use the Java Web Start.
I have modified the jnlp file in order to use my server configuration, and when I access to the browser, just after opening the Kettle splash screen, the app closes without errors. Could you help me with this issue ?

I'm copying the java console output.
