Might also be relevant that I'm instantiating the FXForm from FXML:

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.*?>
<?import com.dooapp.fxform.FXForm?>

<BorderPane xmlns:fx="http://javafx.com/fxml" fx:id="parentPane" styleClass="widget"
    fx:controller="com.foobar.SettingsController">
    <center>
        <FXForm fx:id="metadataForm"/>
    </center>
    <bottom>
        <FlowPane alignment="CENTER" styleClass="buttonBar" hgap="4">
            <Button text="Close" onAction="#close"/>
            <Button text="Re-segment" onAction="#apply"/>
        </FlowPane>
    </bottom>

</BorderPane>

Also, even when running from Eclipse, I get the following warning:

15 [JavaFX Application Thread] INFO com.dooapp.fxform.FXForm - Default resource bundle not found: sun.reflect.NativeConstructorAccessorImpl

Could you attach your build.xml file and controller class com.foobar.SettingsController to help me to reproduce this issue? Thanks.

Sorry for the delay. Missed the message somehow. It seems that the issue has gone away. My apologies for not tracking it more closely.
