      Description



      Name: eaR10174 Date: 10/16/2001


        javax.xml.transform.Transformer throws IllegalArgumentException while processing
      DOMSource object created with zero-argument default constructor (See test.java, case #1
      below), but instead of throwing the exception the Transformer should create an empty
      Document source and transform it. The javadoc description (jdk1.4.0beta-b83) of the
      constructor DOMSource() reads:
        
          "public DOMSource()

           ...
           If this is used, and no DOM source is set, then the Transformer will create an empty
      source Document using DocumentBuilder.newDocument()."
           
        Note that the DOMSource with the manually set empty Document source is transformed
      without any exceptions (See test.java, case #2 below)

        This bug is found in the builds jdk1.4.0-beta3-b83, jaxp-1.1.3 and affects a new JCK1.4
