Definitely needs to be resolved into 4.1.
It seems it is caused by Warning: no known module corresponding to ide5/core/org-netbeans-modules-utilities-cli.jar in /usr/local/home/mp/sources/NetBeans/trunk/nb_all java.io.IOException: Unsupported DOM document implementation! java.lang.ClassNotFoundException: org.apache.xml.serialize.XMLSerializer at org.openide.xml.XMLUtilImpl.handleImplementationException(XMLUtilImpl.java:207) at org.openide.xml.XMLUtilImpl.write(XMLUtilImpl.java:175) at org.openide.xml.XMLUtil.write(XMLUtil.java:298) ... Are you able to reproduce in standard dev build? Did you installed some other modules?
