  A NullPointerException is thrown when creating a property
  extension (lookaside) repository:
  Caused by: java.lang.NullPointerException
  at com.ibm.ws.wim.dao.KeyMana
  ger.getLAKeyForTable(KeyManager.java:207)
  at com.ibm.ws.wim.dao.
  AbstractDAO.createLookAsidePropertyDefinition(AbstractDAO.java:4
  555)
  at com.ibm.ws.wim.lookaside.LookasideAdapter.createSchema(L
  ookasideAdapter.java:1154)
  at com.ibm.ws.wim.SchemaManager.creat
  eSchema(SchemaManager.java:2050)
  at com.ibm.websphere.wim.Servic
  eProvider.createSchema(ServiceProvider.java:205)
  This indicates that the lookaside repository does not contain a
  table being referenced from the database. This can happen if the
  table in the
  database was created with a prefix. In this case, the prefix
  needs to be set in dbSchema in wimconfig.xml.
  

Problem conclusion

• The NullPointerException is no longer thrown. Now a meaningful
  message will print out explaining which table is causing the iss
  and the steps needed to resolve it.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.20 and 9.0.5.8. For more information, see 'Recommended
