B4J Question Button Click Error

In my program I press a button (btnExportExcel_Action) and get the following error:

viewtable._btnexportexcel_action (java line: 78)
java.lang.NoSuchMethodError: com.sun.javafx.css.StyleManager.getPseudoclassMask(Ljava/lang/String;)J
at anywheresoftware.b4a.giuseppe.salvi.dialogs.DialogWrapper$FXDialog$RootPane.<clinit>(DialogWrapper.java:1381)
.......

I just don't understand it. I have buttons in other dialogs in my program and don't see any such issue. This one really throws me.

I'd appreciate any feedback.



Sorry, please ignore - I've localized my problem...
