  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server that use a third party JAXRS         *
    *                  provider that rely on WebSphere JAXRS       *

    ****************************************************************
    * PROBLEM DESCRIPTION: WebSphere JAXRS applications that use   *
    *                      third party JAXRS providers but rely    *
    *                      on WebSphere JAXRS API's may            *
    *                      encounter exceptions.                   *

    * RECOMMENDATION:                                              *
    ****************************************************************
    WebSphere JAXRS applications should use the JAXRS APIs
    corresponding to the JAXRS provider they use.  APAR
    PI75593 corrected the default behavior such that applications
    using third party JAXRS providers could use the correct APIs.
    However, some legacy applications that use third party JAXRS
    providers were written to rely on the APIs delivered with
    WebSphere.   Rather than require potentially complicated
    adjustments to these legacy applications and the environments
    in which they run, this APAR introduces a property
    "com.ibm.websphere.jaxrs.isolateJaxrsThirdPartyImplementations"
    that defaults to "TRUE" but can be set to "FALSE", allowing
    users to revert to the previous behavior.
    

Problem conclusion

  • The property
    "com.ibm.websphere.jaxrs.isolateJaxrsThirdPartyImplementations"
    has been added.  This property will default to "TRUE" but can
    be set to "FALSE" to revert the behavior corrected under APAR
    PI75593 in WebSphere Application Server fix packs 8.5.5.12 and
    9.0.0.4.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 9.0.0.9 and 8.5.5.15  Please refer to the Recommended
