  An array of Objects usage as
a value of the property 'http://java.sun.com/xml/jaxp/properties/schemaSource' causes
StackOverflowError to be thrown (see test.java below). Everything is okey when the
type of the value is either String or InputStream or InputSource or File.
  The bug is found in the patched version of Xerces 2.0.2 release and affects the JAXP
1.2 TCK's TestRun which runs the XMLSchema tests.
