When I used BlueJ, I found a problem with Chinese display.
/javafx.graphics/com/sun/javafx/font/CompositeGlyphMapper.java#getGlyphCode may
return a negative number when no font library is specified in Linux,and this
could cause java.lang.ArrayIndexOutOfBoundsException error.So
javafx.graphics/com/sun/prism/impl/GlyphCache.java#getCachedGlyph shou check
the glyphCode.
The crash demo like this:
`import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Menu;
import javafx.scene.control.MenuBar;
import javafx.scene.control.MenuItem;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class MenuExample extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
BorderPane root = new BorderPane();
Scene scene = new Scene(root,200,300);
MenuBar menubar = new MenuBar();
Menu FileMenu = new Menu("文本");
MenuItem filemenu1=new MenuItem("新建");
MenuItem filemenu2=new MenuItem("Save");
MenuItem filemenu3=new MenuItem("Exit");
Menu EditMenu=new Menu("Edit");
MenuItem EditMenu1=new MenuItem("Cut");
MenuItem EditMenu2=new MenuItem("Copy");
MenuItem EditMenu3=new MenuItem("Paste");
EditMenu.getItems().addAll(EditMenu1,EditMenu2,EditMenu3);
root.setTop(menubar);
FileMenu.getItems().addAll(filemenu1,filemenu2,filemenu3);
menubar.getMenus().addAll(FileMenu,EditMenu);
primaryStage.setScene(scene);
primaryStage.setTitle("TEST");
primaryStage.show();
}
} `
the error:
`java.lang.ArrayIndexOutOfBoundsException: Index -25 out of bounds for length 32
