Error description

  • An application using JPA on WebSphere Application Server
    Network Deployment edition, version 8.5.5.9 is installed on a
    two node cluster. When activating replication of the
    "Object cache instances" used by JPA, every time that cache
    invalidation data gets generated, a
    java.lang.ClassCastException is thrown and the data is not
    invalidated on the remote node.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V8.5.0, V8.5.5, and V9.0.0 who make  *
    *                  use of JPA Criteria API and an L2 cache.    *
    ****************************************************************
    * PROBLEM DESCRIPTION: An OpenJPA ObjectId incompatible with   *
    *                      org.apache.openjpa.datacache.QueryKey   *
    *                      issue occurs during serialization.      *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When the OpenJPA DataCache is enabled
    ("openjpa.DataCache=true"), and a Criteria Query is created,
    there exists the chance that the corresponding QueryKey for
    the Criteria Query will cause serialization issues. This issue
    ultimately sufaces as a ClassCastException. In most cases a
    Criteria Query is never serialized. However, when the OpenJPA
    DataCache is enabled, and a distribued L2 cache, such as
    DynaCache is used, the Criteria Query might be serialzed. The
    reported exception will appears as follows:
    java.lang.ClassCastException
    java.lang.ClassCastException:org.apache.openjpa.util.ObjectId
    incompatible with org.apache.openjpa.datacache.QueryKey
    The root exception will appear as follows:
    Caused by: java.io.NotSerializableException:
    org.apache.openjpa.persistence.criteria.CriteriaQueryImpl
    

Problem conclusion

  • With this fix, code has been added to OpenJPA to ensure that a
    Criteria Query is properly serialized when OpenJPA DataCache
    is enabled.
    
    The fix for this APAR is currently targeted for inclusion in
    Service Levels (Fix Packs) 8.5.5.12 and 9.0.0.3 of WebSphere
    Application Server versions 8.5.5 and 9.0.0, and fix pack
    16.0.0.4 for WebSphere Application Server Liberty.
