PM00467: CRC IS NOT UPDATED AFTER RESAVING CONTENT WITH PK94337 AND PK98507

 

APAR status

  • Closed as program error.

Error description

  • CRC is not updated after resaving content with PK94337 and
    PK98507
    Enable the following trace com.aptrix.util.*=finest and watch
    logs for traces related to invalid CRC.  Save and access the
    same item and the exception is repeated.
    Save does not correctly set the CRC if the item was created
    before PK94337 was applied and the CRC was initialy set to 0.

Problem summary

Problem conclusion

  • Detailed Problem Description:
    Sun JDK 1.4.2_15 b01 and above include a fix for sun bug id
    4879507.  This fix results in changes to ZipInputStream to check
    the CRC for stored (uncompressed) files.  The CRC for stored
    (uncompressed) files was not previously checked by the Sun JDK.
    The CRC was not being set correctly by WCM and therefore
    customers experienced the issues documented in APARs PK94337 and
    PK98507.
    Problem Analysis:
    PK94337 ensures that newly created content is stored with the
    CRC as expected and PK98507 handles and allows customer's to
    render and access items that do not have the proper CRC.  In
    order to handle these items WCM has added exception handling
    that allows WCM to continue rendering the data as expected.
    However, it is recommended that customer's resave this content
    at some point to ensure the CRC is properly set and to avoid any
    additional overhead added by the exception handling that results
    from the invalid CRCs.
    .
    Affected Users:
    All users.  The CRC checking is however only added to the Sun
    JDK and therefore customer's running on Solaris with JDK
    1.4.2_15(b01)  or higher are affected by the outward symptoms
    (CRC errors and exception handling).  Other environments will
    not have the correct CRC set on old content until it is resaved
    but the outward symptoms will not be present.
