SchemaFactory.newSchema throws InternalError in case of DOMSource

Name: eaR10174 Date: 12/22/2003


The method

     javax.xml.validation.SchemaFactory.newSchema(Source[] schemas)

throws InternalError in case when a Schema object is created from DOMSource.
The method should support DOMSource inputs according to the javadoc.

The bug affects new JCK1.5 tests (not integrated yet):

   api/javax_xml/validation/SchemaFactory/index.html#NewSchema[NewSchema005]
   api/javax_xml/validation/SchemaFactory/index.html#NewSchema[NewSchema006]

The following test fails running on JDK 1.5.0-beta-b32.
See below the test source and the execution log:
