java.util.ConcurrentModificationException
Key: BATIK-1049
URL: https://issues.apache.org/jira/browse/BATIK-1049
Project: Batik
Issue Type: Bug
Components: SVG DOM
Affects Versions: 1.7
Environment: jdk1.7.10 ubuntu 12.04 batik 1.7
Reporter: angry
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));
