Updated issue title to reflect that this is not about ClassNotFoundExceptions (anymore).

Original comment by A. Walter (Bitbucket: awalterwork, GitHub: Unknown):


Update:

Thanks to https://bugs.openjdk.java.net/browse/JDK-8122760 , I figured out that the custom controls should set the class loader for the FXML loaders they create in their constructors. I did so by adding "loader.setClassLoader(this.getClass().getClassLoader());" to their constructors right after the FXML loaders were created.

This indeed fixed the ClassNotFoundExceptions when loading the resulting JAR. (I committed the updated code and the resulting JAR in the repository linked in the question.)

However, it is still not possible to open the FXML file that uses the nested custom controls because of a new LoadException, going back to a ClassCastException in this case, based in SceneBuilder code:

OutermostFxml.fxml is:

#!xml

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.geometry.Insets?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.HBox?>
<?import javafx.scene.layout.VBox?>
<?import java.lang.*?>
<?import nestedCustomControlsFxml.*?>
<?import javafx.collections.*?>

<OuterCustomControl fx:id="Including" prefHeight="1080.0" prefWidth="1920.0"
    xmlns="http://javafx.com/javafx/8.0.101" xmlns:fx="http://javafx.com/fxml/1">

    <innerCustomControl>
        <toolbarContent>
            <Button text="Test from Outermost Fxml"></Button>
        </toolbarContent> <!-- this is line 19 -->
    </innerCustomControl>

</OuterCustomControl>

Line 19 is indicated by the LoadException , which is where a tag defined by InnerCustomControl is closed.

As OutermostFxml.fxml can be successfully loaded and displayed by a JavaFx application and the class loader issue was corrected, this indeed appears to be a SceneBuilder problem.

Hi folks, any progress on this issue?

I don't think this is the exact issue you were having, but if it helps anyone else, when I made my java package names start with a capital letter this started happening to me. Changing them to be lowercase fixed the issue. Eg i had: main/FXML/Views/CustomView.java but i had to change it to: main/fxml/views/CustomView.java
