Here is my code!
package sample;
import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.scene.Group; import javafx.scene.Parent; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.VBox; import javafx.scene.text.Text; import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
//Parent proot = FXMLLoader.load(getClass().getResource("sample.fxml"));
Group root = new Group();
Text text = new Text("Sup?");
root.getChildren().add(text);
primaryStage.setTitle("Sup");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.show();

56,414 PointsI did a little research on this and it looks like this is a bug specific to the Mac and Java 7 JDK. It's supposed to be fixed in the latest version of OpenJDK 7 (u95 or higher, the Oracle JDK ended public updates for 7), so I'd suggest updating your Java installation to that or a Java 8 SDK.
Bug details: https://bugs.openjdk.java.net/browse/JDK-8143907

7,821 PointsFor anyone that still may be experiencing this issue and doesn't want to update to SDK 8, stackoverflow offered an acceptable workaround. In the main method add the following:
try {
Class<?> macFontFinderClass = Class.forName("com.sun.t2k.MacFontFinder");
Field psNameToPathMap = macFontFinderClass.getDeclaredField("psNameToPathMap");
psNameToPathMap.setAccessible(true);
psNameToPathMap.set(null, new HashMap<String, String>());
} catch (Exception e) {
}
