WindowBuilder:Anonymous class creation can not be evaluated.

WindowBuilder的对包含匿名类的java代码支持不太好，

    protected void createContents() {
        shell = new Shell(SWT.NO_TRIM | SWT.ON_TOP);        
        shell.setSize(648, 480);
        shell.setText("标签编译器");

        shell.addKeyListener(keyListener);
        // 匿名类方式初始化globalListenerManager 
        GlobalListenerManager globalListenerManager = new GlobalListenerManager(){
            private static final long serialVersionUID = 1L;
            {put(SWT.KeyDown,keyListener);}         
        };
        Rectangle[] rects = new Rectangle[]{
                new Rectangle(50,50,200,200),
                new Rectangle(350,100,150,250),
                new Rectangle(125,300,200,321)};
        Image image = SWTResourceManager.getImage(this.getClass(),"/image/562c11dfa9ec8a13f075f10cf303918fa1ecc0eb.jpg");
        shell.setLayout(new FillLayout(SWT.HORIZONTAL));
        ActiveRectEditor editor = new ActiveRectEditor(shell, SWT.NONE,image,rects, globalListenerManager);
    }

上面的代码在WindowBuilder的Design界面下报错了

点击左下角的红X显示了错误信息，如下图：

将globalListenerManager 的匿名类的初始化方式

        GlobalListenerManager globalListenerManager = new GlobalListenerManager(){
            private static final long serialVersionUID = 1L;
            {put(SWT.KeyDown,keyListener);}     

改为正常的初始化就好。

GlobalListenerManager globalListenerManager = new GlobalListenerManager();
globalListenerManager.put(SWT.KeyDown,keyListener);

其实这原来的代码是没毛病的，只是在windowbuilder的Design解释器无法支持。
