Modular JavaFX does not export com.sun.javafx.css

[cbm64chris]

In a modular JavaFX project, it is not possible to use this very useful project.

Caused by: java.lang.IllegalAccessError: class org.google.jhsheets.filtered.tablecolumn.editor.FilterMenuPopup (in module javafx.filterable.table.columns) cannot access class com.sun.javafx.css.StyleManager (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.css to module javafx.filterable.table.columns

AdoptOpenJDK 12 JavaFX 12

@cbm64chris I just stumbled across the same problem and the problem seem to be 2 classes that import com.sun.javafx.css.StyleManager to apply css.

1. I changed FilterMenuPopup.java from

   public class FilterMenuPopup extends PopupControl
   {
   static {
       StyleManager.getInstance().addUserAgentStylesheet(FilterMenuPopup.class.getResource(FilterMenuPopup.class.getSimpleName() + ".css").toString());
   }
   
   public FilterMenuPopup(String title) 
   {
   }
   }

   to

   public class FilterMenuPopup extends PopupControl
   {
   public FilterMenuPopup(String title) 
   {
       ((Parent) getStyleableNode()).getStylesheets()
               .add(FilterMenuPopup.class.getResource(FilterMenuPopup.class.getSimpleName() + ".css").toString());
   }
   }

2. Also, I changed FilterMenuButton .java from

   public class FilterMenuButton extends Button
   {
   static {
   StyleManager.getInstance().addUserAgentStylesheet(FilterMenuButton.class.getResource(FilterMenuButton.class.getSimpleName() + ".css").toString());
   }
   
   public FilterMenuButton(final FilterMenuPopup popup)
   {
   }
   }

   to

   public class FilterMenuButton extends Button
   {
   public FilterMenuButton(final FilterMenuPopup popup)
   {
       getStylesheets().add(FilterMenuButton.class.getResource(FilterMenuButton.class.getSimpleName() + ".css").toString());
   }
   }

   It works for me, comes without warranty. 😃
