APAR status

• Closed as program error.

Error description

• The cause of the problem is that the thread context class loader
  is set
  to an application class loader that has overriden the XML parser
  implementation.  The application code calls SIB, which calls SM,
  which
  calls EMF to read an XML document, which uses the incompatible
  XML
  parser implementation, which causes a ClassCastException.
