APAR status

  • Closed as program error.

Error description

  • During 18.0.0.2 development a change was made to wimcore-1.0
    (a
    private feature included by federatedRegistry and
    ldapRegistry)
    to include Liberty's internal copy of JAX-B in preparation
    for
    Java 9+ support.
    

Local fix

  • Enable the public jaxb-2.2 feature and rely on the JDK copy
    of JAXB

    After upgrading from 18.0.0.1 to 18.0.0.2, some users
    encountered a JAXB error when we try to explicitly load
    JAXBContext. The issue typically occured on application startup
    time, with a stack trace as follows:
    
    java.lang.Error: javax.xml.bind.JAXBException: Unable to create
    context

Problem conclusion

  • In preparation for Java 11 support, where JAX-B is being removed
    from the JDK, internal refactoring was ocurring on Liberty
    components. As a result of this refactoring, a split package
    classloading conflict started to occur for applications which
    packaged their own implementation of JAX-B.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 18.0.0.3.  Please refer to the Recommended Updates page for
    delivery information:
