IV46281: JAXB MARSHALLER SETTING XSI:NIL ATTRIBUTE AS 'TRUE' FOR ELEMENTS WHICH ARE HAVING NON NILLABLE VALUE AFTER APPLYING JAVA 6 SR8

APAR status

• Closed as program error.

Error description

• Error Message: The problem is found while an UnMarshaller o/p is
  being fed as input for Marshaller. The Marshaller will produce
  xsi:nill="true" for those elements having a value with
  UnMarshalled o/p.
  For example, for if an unmarshaller o/p is
  <ns2:ImageCaptureDetail xmlns:ns2="http://test.com//sample">
   <ns2:CaptureDate
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:nil="true"/>
   <ns2:CaptureResolutionCode ></ns2:CaptureResolutionCode>
  </ns2:ImageCaptureDetail>
  The JAXB marshaller will produce
  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
  <ImageCaptureDetail xmlns="http://test.com//sample">
      <CaptureDate
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:nil="true"/>
      <CaptureResolutionCode
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:nil="true">1</CaptureResolutionCode>
  </ImageCaptureDetail>
  Here with marhsaller o/p CaptureResolutionCode should not have
  xsi:nil attribute as the element is having data. The problem
  happens for JAXBElement wrapping which is being done by XJC. The
  issue is not happening for List (ArrayList) or for plain object
  type.
  .
  Stack Trace: N/A
  .
  

Local fix

• Modify schema to include maxOccurs="unbounded" for problematic
  elements or avoid using substitutionGroup elements with
  attribute.
  

Problem summary

• The problem happens as 'nil' state variable inside JAXB
  unmarshaller implementation is not being reset during XML
  element push and pop operation. The value set for previous
  element is being carry forwarded for the next elements.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR15
  7.0.0 SR6
  6.0.1 SR7
  .
  Change is being made to reset 'nil' state variable inside IBM
  JVM JAXB unmarshaller implementation correctly.
  

Temporary fix
