        Description

        Name: eaR10174 Date: 10/10/2001


          javax.xml.transform.Transformer.setOutputProperties(Properties oformat) does not revert
        the values of changed properties to values defined in the stylesheet when the argument
        'oformat' is null (See test.java below). The javadoc description of the method
        Transformer.setOutputProperties() (jdk1.4.0beta-b82) reads:

         "public abstract void setOutputProperties(Properties oformat)
                                          throws IllegalArgumentException
             ...
             If argument to this function is null, any properties previously set are removed, and
             the value will revert to the value defined in the templates object."

          This bug is found in the builds jdk1.4.0-beta3-b82, jaxp-1.1.3 and affects a new JCK1.4
