   The javax.xml.validation.ValidationHandler does not invoke the method
ignorableWhitespace() of the user-defined ContentHandler (see test.java below)
in case when there are whitespaces in the element content. The method should be invoked
according to the javadoc:

      public abstract void setContentHandler(org.xml.sax.ContentHandler receiver)

      ...
      A ValidatorHandler may buffer events to certain extent, but to allow
      ValidatorHandler to be used by a parser, the following requirement has to
      be met.

        ...
        4. If ValidatorHandler determines that certain characters are "ignorable
        whitespace", it should invoke the
        ContentHandler.ignorableWhitespace(char[], int, int) callback instead of
        the ContentHandler.characters(char[], int, int) callback. This is
        necessary for a DocumentBuilder to properly implement
        org.w3c.dom.Text#isWhitespaceInElementContent().

The bug appears in jdk1.5.0beta-b31 and affects a new JCK1.5 test:

api/javax_xml/validation/ValidatorHandler/index.html#GetSetContentHandler[GetSetContentHandler008]
