I get the following exception when changing the font of a SwingTextField. I've a Slider which changes the size of the font used by SwingTextField. When slider position is reduced to 0, exception is thrown

Unexpected exception caught in MasterTimer.timePulse():

Below is the testcase. When Stage comes up, move the slider knob to left end and exception will be thrown.

import javafx.ext.swing.*;
import javafx.stage.*;
import javafx.scene.*;
import javafx.scene.text.*;

var font = Font {
    name: "Dialog"
    size: 12
};
var tf = SwingTextField {
    text: "Some text"
    columns: 15
    font: bind font
    translateX: 30
    translateY: 40
};
var size = 12 on replace {
    font = Font {
        name: "Dialog"
        size: size
    };
};
Stage {
    scene: Scene {
        content: [tf, SwingSlider {
            minimum: 0
            maximum: 50
            value: bind size with inverse
            translateX: 30
            translateY: 100
        }]
    }
    width: 300
    height: 200
    visible: true
}
