Local fix

• N/A
  

Problem summary

• The problem is caused while code is unable to process xsi:type
  correctly while IZ69790 applied. A new JAXBContext property
  JAXBRIContext.IMPROVED_XSI_TYPE_HANDLING (or system property
  "com.sun.xml.bind.improvedXsiTypeHandling") is being introduced
  to handle xsi:type on XMl leaf elements based on condition.
  Setting this property true/false will enabled/disabled xsi:type
  handling while creating the JAXBContext.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR11
  6.0.1 SR3
  .
  JVM has been modified to update IMPROVED_XSI_TYPE_HANDLING
  property value while creating the context .
