PK80674: NULLPOINTEREXCEPTION OCCURS DURING UNMARSHAL WHEN USING THE JAX-WS THIN CLIENT

Fixes are available

APAR status

Closed as program error.

Error description

The JAXB API, javax.xml.bind.JAXBContext, controls the
marshaling and unmarshaling of XML data.  The JAXBContext is
initialized with a series of package names of the user's JAXB
classes.  If the user does not provide a complete list of
package names, the JAXBContext inspects the user's JAXB
classes to find the missing packages.  In some cases this may
result in a java.lang.NullPointerException while using the
JAXBContext to unmarshal XML data.

Local fix

The code to work around this problem is to take the XML and
Parse in the org.w3c.dom.Document before Unmarshalling.

Problem summary

The JAXB API, javax.xml.bind.JAXBContext, controls the
marshaling and unmarshaling of XML data.  The JAXBContext is
initialized with a series of package names of the user's JAXB
classes.  If the user does not provide a complete list of
package names, the JAXBContext inspects the user's JAXB
classes to find the missing packages.

If a user does not provide a complete list of packages, the
following error may occur while using the JAXBContext to
unmarshal XML data.  Example:

java.lang.NullPointerException

The JAXBContext API is embedded with the JAX-WS runtime and
other stack software.  It is possible that customers may
receive the above error even if they are not directly using
JAXB.

Problem conclusion

The IBM implementation of the JAXBContext failed to
discover the missing JAXB classes in some rare cases.  A
subsequent attempt to unmarshal XML failed with the
NullPointerException described in the Problem Summary.

The IBM implementation of the JAXBContext is corrected to find
the missing JAXB classes.  The indicated NullPointerException
error will no longer occur.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.5.  Please refer to the Recommended Updates
