Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All IBM WebSphere Application Server V7.0   *
    *                  users of JAX-WS and JAXB.                   *
    ****************************************************************
    * PROBLEM DESCRIPTION: The JAXB Unmarshaller may throw a       *
    *                      RuntimeException.                       *
    ****************************************************************
    * RECOMMENDATION:  Install a fix pack that contains this       *
    *                  APAR.                                       *
    ****************************************************************
    The IBM JAXB Unmarshaller may attempt to generate code at
    runtime which casts a java.lang.String to a byte[]. As a
    result, the Unmarshaller may throw a RuntimeException since
    those types are not compatible:
    java.lang.RuntimeException: FCG BCEL feature is unimplemented
    at
    com.ibm.fcg.impl.FinalCodeGenerator.unimplementedException(Unkno
    wn
    Source) at
    com.ibm.fcg.impl.FinalCodeGenerator.genCode_coerce(Unknown

    tubGeneratorHelper.callJAXBFactory(FCGDeserializationStubGenerat
    orHelper.java:186)
    

Problem conclusion

  • The issue was corrected by changing the IBM JAXB Unmarshaller
    so that it no longer attempts to generate code which ilegally
    casts a java.lang.String to a byte[].
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.19.  Please refer to the Recommended Updates
    page for delivery information:
