Look And Feel/Theme not working for 2019.12.1

I can’t upgrade Java until I upgrade Servoy from 8.3.3 to 2019.12.1. In 8.3.3, I can open the Admin page and enter for selectedlnf ‘javax.swing.plaf.metal.MetalLookAndFeel’ and for lnf.theme ‘com.incors.plaf.kunststoff.themes.KunststoffDesktopTheme’. After saving and restarting Developer, the solutions looks correct in the Form Editor and in the Smart Client preview. This is not the case in 2019.12.1 for things like comboboxes, tabs, check boxes, etc. Is this no longer a supported feature, am I missing a step or am I doing something wrong?

From 8.3.3:

what is in your “application_server\lafs” ?

if you want to use kunstoff you have to have there that jar, by default we don’t ship that anymore, so you need to take that from an older version

The file kunststoff.jar is and has been present in the application_server\lafs folder. I have tried the file from my 8.3.3. install as well as one I downloaded from http://www.java2s.com/Code/Jar/k/Downlo … offjar.htm. I even unzipped the jar to make sure that com.incors.plaf.kunststoff.themes.KunststoffDesktopTheme’ is there and it is. Still not working.
