      Description



      Name: eaR10174 Date: 02/20/2004


         The javax.xml.validation.SchemaFactory.newSchema(Source[]) method throws an exception that is not
      equal to the exception thrown from LSResourceResolver (see test.java below). The exceptions should be the
      same according to the javadoc:

            public abstract void setResourceResolver(LSResourceResolver resourceResolver)

            ...
            If a LSResourceResolver throws a RuntimeException (or instances of its derived classes),
            then the SchemaFactory will abort the parsing and the caller of the newSchema method will
            receive the same RuntimeException.

      The bug affects the new JCK1.5-beta1 test:

          api/javax_xml/validation/SchemaFactory/index.html#NewSchema[NewSchema015]

      This test has been in the known failures list with the bug #4969089.

      The sample is provided below; it fails on JDK 1.5.0-beta-b39.
