Local fix

• 1.Backup the upgrade.xml under
  /usr/IBM/WebSphere/BPM85/util/dbUpgrade/upgrade.xml
  2.In order to avoid the further classnotfound issue, please
  help add below jars into the upgrade.xml
  <path id="upgrade.classpath">
  <fileset dir="${was.install.root}/plugins">
  <include name="com.ibm.bpm.sca.jar"/>
  <include name="com.ibm.bpc.runtime"/>
  ......
  </fileset>
  ......
  </path>
  3.Re-run the dbupgrade. Make sure you have taken a good backup
  of your database before you rerun the dbupgrade.
  

Problem summary

• This issue occurs because com.ibm.bpm.sca.core.SCARuntime was
  persisted in the W_TASK_EXECUTION_CONTEXT, but the upgrade.xml
  file didn't include a reference to the com.ibm.bpm.sca.jar file.
  

Problem conclusion

• A fix is available for IBM BPM V8.5.5.0 that adds
  com.ibm.bpm.sca.jar to the upgrade.xml file to avoid the error.
