http://issues.apache.org/bugzilla/show_bug.cgi?id=27687 NodeList not thread safe Summary: NodeList not thread safe Product: Xerces-J Version: 1.2.3 Platform: Sun OS/Version: Solaris Status: NEW Severity: Critical Priority: Other Component: Core AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] The NodeList implementation is not thread safe. When iterating through children of a particular node, the NodeList gets changed by another thread doing the same action. As a result I get a NullPointerException sometimes and some other times I get "wrong document error" when I try to append this clone a child node to a document. The first implementation to access children of a node does not work. NodeList childList=root.getChildNodes(); for (int i=0; i<childList.getLength(); i++) { // doing something here with "childList.item(i)" } The second implementation to access children of a node works. Node currChildNode = root.getFirstChild(); while(currChildNode != null) { // Do something here with the "currChildNode" currChildNode = currChildNode.getNextSibling(); } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
