调整含有JSVGCanvas在JComponent时蜡染IllegalStateException异

我的计划似乎运作得很好，但我不断收到“IllegalStateExceptions：RunnableQueue未启动或已退出”不时，当我尝试调整我的组件。我已经设置了documentState到ALWAYS_DYNAMIC，我已阅读，你应该使用JSVGCanvas' UpdateManager和调用的invokeLater（）。据我所知，这是第一个可用的时间之后

gvtBuildCompleted(GVTTreeBuilderEvent e)

是所谓的，所以我检查之前，我使用它，但我仍然得到异常是否正在运行。下面的方法是通过反复线程调用，似乎会导致异常：

private void updateDomTree(final SVGComponent component, final Document doc)
{
if(component.getSvgCanvas().getUpdateManager() != null && component.getSvgCanvas().getUpdateManager().isRunning())
{
    component.getSvgCanvas().getUpdateManager().getUpdateRunnableQueue().invokeLater(new Runnable() 
    {
        public void run() 
        {
            final Node newNode = doc.getChildNodes().item(0).getFirstChild();
            //could be easier to get this value, but ... it works.
            String newNodeId = newNode.getAttributes().getNamedItem("id").getFirstChild().getNodeValue();

            NodeList nodes = component.getSvgDocument().getDocumentElement().getChildNodes();
            Node updateNode = findElementById(nodes, newNodeId);
            resizeComponent(component, doc);
            component.getSvgCanvas().getSVGDocument().adoptNode(newNode);
            component.getSvgCanvas().getSVGDocument().getDocumentElement().replaceChild(newNode, updateNode);
            component.refreshSVGCanvas();
        }
    });
}
}

实际调整大小都是在这里完成：

protected void resizeComponent(SVGComponent component, Document doc)
{
    Element svgRoot = doc.getDocumentElement();
    final int svgWidth = Integer.parseInt(svgRoot.getAttribute("width"));
    final int svgHeight = Integer.parseInt(svgRoot.getAttribute("height"));
    String[] viewBox = svgRoot.getAttribute("viewBox").split(" ");
    int viewBoxLeft = Integer.parseInt(viewBox[0]);
    int viewBoxTop = Integer.parseInt(viewBox[1]);
    final float factor = component.getScaleFactor();
    String[] viewBoxOld = component.getSvgDocument().getDocumentElement().getAttribute("viewBox").split(" ");
    int viewBoxLeftOld = Integer.parseInt(viewBoxOld[0]);
    int viewBoxTopOld = Integer.parseInt(viewBoxOld[1]);
    int xDiff = (int) ((viewBoxLeftOld - viewBoxLeft)*factor);
    int yDiff = (int) ((viewBoxTopOld - viewBoxTop)*factor);

    if ( viewBoxLeftOld != viewBoxLeft ) //If there is additional content left
    {
        component.setLocation(component.getLocation().x - xDiff, component.getLocation().y);
    }
    if ( viewBoxTopOld != viewBoxTop ) //If there is additional content right)
    {
        component.setLocation(component.getLocation().x, component.getLocation().y - yDiff);
    }

    component.getSvgDocument().getDocumentElement().setAttribute("width",""+svgWidth);
    component.getSvgDocument().getDocumentElement().setAttribute("height",""+svgHeight);
    component.getSvgDocument().getDocumentElement().setAttribute("viewBox", ""+viewBoxLeft+" "+viewBoxTop+" "+svgWidth+" "+svgHeight);
    component.setSize((int)(svgWidth*factor),(int)(svgHeight*factor));
}

方法

refreshJSVGCanvas()

电话

JSVGCanvas.setDocument(Document);
JSVGCanvas.setSize(int, int);

在此先感谢，我已经找遍和尝试了很多，但无法找到一个解决方案。

编辑：这是蜡染的invokeLater-方法，其中唯一的例外是实际抛出：

public void invokeLater(Runnable r) {
    if (runnableQueueThread == null) {
        throw new IllegalStateException
            ("RunnableQueue not started or has exited");
    }
    synchronized (list) {
        list.push(new Link(r));
        list.notify();
    }
}

runnableQueueThrad设置该类的run（）的内部 - 的方法和在端部设置为空。所以我想我必须做某种同步。

大胆猜测，“公共无效的run（）”的代码不应该是内部的另一种方法，真的是一个线程类/界面对象的所谓的构造函数（接口版本实际上）。

它删除其自己的类（如嵌套子类保护范围），并实现类上的“线程可运行”界面发出“运行（）”方法，它用。

堆栈跟踪说，因为它实际上并没有这样的方法（或至少不正确申报），所以它是一个“非法状态” run方法不可用。
