8286867: Update #getGlyphCode return a negative number

[Tomator01]

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 at com.sun.prism.impl.GlyphCache.getCachedGlyph(GlyphCache.java:332) at com.sun.prism.impl.GlyphCache.render(GlyphCache.java:148) at com.sun.prism.impl.ps.BaseShaderGraphics.drawString(BaseShaderGraphics.java:2101) at com.sun.javafx.sg.prism.NGText.renderText(NGText.java:312) at com.sun.javafx.sg.prism.NGText.renderContent2D(NGText.java:270) at com.sun.javafx.sg.prism.NGShape.renderContent(NGShape.java:261) at com.sun.javafx.sg.prism.NGNode.doRender(NGNode.java:2072) at com.sun.javafx.sg.prism.NGNode.render(NGNode.java:1964) at com.sun.javafx.sg.prism.NGGroup.renderContent(NGGroup.java:270) at com.sun.javafx.sg.prism.NGRegion.renderContent(NGRegion.java:578) at com.sun.javafx.sg.prism.NGNode.doRender(NGNode.java:2072) at com.sun.javafx.sg.prism.NGNode.render(NGNode.java:1964) at com.sun.javafx.sg.prism.NGGroup.renderContent(NGGroup.java:270) at com.sun.javafx.sg.prism.NGRegion.renderContent(NGRegion.java:578) at com.sun.javafx.sg.prism.NGNode.doRender(NGNode.java:2072) at com.sun.javafx.sg.prism.NGNode.render(NGNode.java:1964) at com.sun.javafx.sg.prism.NGGroup.renderContent(NGGroup.java:270) at com.sun.javafx.sg.prism.NGRegion.renderContent(NGRegion.java:578) at com.sun.javafx.sg.prism.NGNode.doRender(NGNode.java:2072) at com.sun.javafx.sg.prism.NGNode.render(NGNode.java:1964) at com.sun.javafx.sg.prism.NGGroup.renderContent(NGGroup.java:270) at com.sun.javafx.sg.prism.NGRegion.renderContent(NGRegion.java:578) at com.sun.javafx.sg.prism.NGNode.doRender(NGNode.java:2072) at com.sun.javafx.sg.prism.NGNode.render(NGNode.java:1964) at com.sun.javafx.sg.prism.NGGroup.renderContent(NGGroup.java:270) at com.sun.javafx.sg.prism.NGRegion.renderContent(NGRegion.java:578) at com.sun.javafx.sg.prism.NGNode.doRender(NGNode.java:2072) at com.sun.javafx.sg.prism.NGNode.render(NGNode.java:1964) at com.sun.javafx.tk.quantum.ViewPainter.doPaint(ViewPainter.java:479) at com.sun.javafx.tk.quantum.ViewPainter.paintImpl(ViewPainter.java:328) at com.sun.javafx.tk.quantum.PresentingPainter.run(PresentingPainter.java:91)

Hello,i have signed oca ,and pull /signed command ,so I'm just wait for OCA to pass？

[yososs]

Reading the author's description of this PR, one wonders why the added condition is not "glyphCode < 0".

if (glyphCode <= 0) {return null;}

Your suggestion is right
