Button Width Calculated Wrong under Windows?

DaytonaJohn

I am developing a JavaFX application under Java 8 on my Ubuntu 14.04 (32 bit) system. When I run it on the Ubuntu box, all is fine, but when I run it under Windows 7 Home Premium (64 bit) with the same Java8 release installed, all my buttons have their text ellipsised (sp?).  Any ideas on why the behavior is different? Or is this a bug in JavaFX? Here are the particulars:

fxml:

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

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.text.*?>

<AnchorPane id="AnchorPane" prefHeight="91.0" prefWidth="-1.0" xmlns:fx="http://javafx.com/fxml">
  <children>
    <VBox alignment="CENTER" prefHeight="91.0" prefWidth="-1.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
      <children>
        <Label fx:id="tripleButtonText" alignment="TOP_CENTER" contentDisplay="CENTER" prefWidth="-1.0" text="This is some text.&#10;There may be several lines." textAlignment="CENTER" />
        <HBox alignment="CENTER" fillHeight="false" prefHeight="22.0" prefWidth="-1.0" spacing="10.0" VBox.vgrow="NEVER">
          <children>
            <Button fx:id="tripleButton1" contentDisplay="CENTER" mnemonicParsing="false" text="Button" prefWidth="-1.0" textAlignment="CENTER" HBox.hgrow="ALWAYS" />
            <Button fx:id="tripleButton2" contentDisplay="CENTER" mnemonicParsing="false" text="Button" prefWidth="-1.0" textAlignment="CENTER" HBox.hgrow="ALWAYS" />
            <Button fx:id="tripleButton3" contentDisplay="CENTER" mnemonicParsing="false" text="Button" prefWidth="-1.0" textAlignment="CENTER" HBox.hgrow="ALWAYS" />
          </children>
          <VBox.margin>
            <Insets top="14.0" />
          </VBox.margin>
        </HBox>
      </children>
    </VBox>
  </children>
</AnchorPane>

Turns out this problem only shows up with StageStyle.UTILITY. Any other StageStyle works fine. Sounds like a bug to me.
