Transformer.newTransformer(DOMSource) throws java.lang.NullPointerException

Name: eaR10174 Date: 01/29/2001


   JAXP 1.1 method javax.xml.transform.Transformer.newTransformer(DOMSource) throws
java.lang.NullPointerException (see test.java below).
   
   This bug appears in build jaxp-1.1-b18-26_jan_2001 and affects the new test in TCK JAXP 1.1
  
     api/javax_xml_transform/dom/DOMLocator/index.html#getOriginatingNode()
     
   If "tfactory.setErrorListener(myErrorListener)" is commented the test program executes without
   java.lang.NullPointerException.
