Comment 1 Jesse Glick 2004-08-09 16:12:15 UTC 
Looks like some bug in Xerces - NB code is just call
NodeList.get(int). Never seen it, no info on how to reproduce, not
even JDK version or log file etc.
Comment 2 bwl 2005-02-03 06:12:59 UTC 
FYI, we've had this same error (in non-NetBeans code) and searching
the web I turned up this: http://www.xml-xerces.com/msg/2734.html
which indicates that it very likely is a Xerces bug.  Another
possibility is concurrent access to the same DOM from multiple threads.
