You get these errors because the classes of the ij.* package are not
imported by default any more by the script editor.

I just discovered that there is an option to switch the auto-imports
back on: in Fiji's script editor, go to:

*Edit > Auto-import (deprecated)*


In any case, it might be a good idea to not trust the auto-imports but
import the classes you need explicitly:

     importClass(Packages.ij.IJ);
     importClass(Packages.ij.gui.GenericDialog);

Hope that helps,
Jan
