Local fix

Problem summary

  • The hashing algorithm used internally by the processor was
    updated to be more secure.  However this means that
    stylesheetsprecompiled with an older processor will not run with
    a newer processor that uses the new hashing.  A Java system
    property,com.ibm.xtq.processor.disableSecureHash, has been
    provided to switch back to the old style hashing when set to
    'true' (-Dcom.ibm.xtq.processor.disableSecureHash=true).
    

Problem conclusion

  • New Java system property allows old precompiled stylesheets to
    work with newer processors.
