Description

I got the exception when modifying the dom in updatemanger queue.
But notice that : the exception is not always throwed, it really hard to catch that. we met twice, in about six monthes.

code:
WarnLevel wl = content.getLevel();
Element textNode = doc.getElementById(elementId + "_bubble1_text");
Element imgNode = doc.getElementById(elementId + "_bubble1_image");
//this is the place where the error occur
imgNode.setAttributeNS(SVGUtils.XLinkNameSpace, "xlink:href", "#" + wl.name() + "_gridnt_bubble");
NodeList list = textNode.getChildNodes();
int total = 0;
for (String msg : msgs) {
int temp = Integer.parseInt(msg);
total += temp;
}
((org.apache.batik.dom.GenericText) list.item(0)).setData(Integer.toString(total));
