PM15844: JAXB Unmarshaller may fail to parse some hexBinary values

Fixes are available

APAR status

Closed as program error.

Error description

When a field is declared as xs:hexBinary in a JAXB class,
the JAXB Unmarshaller may fail to parse values for this field,
either resulting in loss of data or an incorrect value returned.

Problem summary

****************************************************************
* USERS AFFECTED:  All IBM WebSphere Application Server V7.0   *
*                  users of JAXB and JAX-WS.                   *
****************************************************************
* PROBLEM DESCRIPTION: The JAXB runtime sometimes loses        *
*                      xs:hexBinary values or unmarshals       *
*                      them incorrectly.                       *
****************************************************************
* RECOMMENDATION:  Install a fix pack that contains this APAR. *
****************************************************************
When an application's JAXB classes contain fields whose
schema type is xs:hexBinary, the JAXB Unmarshaller may
interpret those fields as being xs:base64Binary, resulting in
loss of data or an incorrect value returned.

Problem conclusion

In JAXB the xs:hexBinary type is expressed as an annotation
@XmlJavaTypeAdapter(HexBinaryAdapter.class). The IBM JAXB
runtime was failing to read this annotation when it appears on
the create*() methods of the ObjectFactory and was mistakenly
mapping the property to xs:base64Binary (the default binding
when there is no @XmlJavaTypeAdapter). With the wrong type
information, the Unmarshaller would either fail to parse values
into a byte[] or produce the wrong value.

The problem was resolved by correcting the processing logic
for ObjectFactory classes, ensuring that any
@XmlJavaTypeAdapter annotations on the create*() methods be
taken into account when determining the schema type of a
property.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.13.  Please refer to the Recommended Updates
