Transformer doesn't transform an empty StreamSource

Name: eaR10174 Date: 10/16/2001


  javax.xml.transform.Transformer does not transform an empty StreamSource, it throws a
TransformerException (See test.java below).
  The javadoc description (jdk1.4.0beta-b83) of the constructor StreamSource() reads:
  
   "public StreamSource()
    ...
    If this constructor is used, and no other method is called, the Transformer assumes an
empty input tree, with a default root node."

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