Error description

  Exception:javax.naming.NamingException
  SourceId:com.ibm.ws.naming.util.Helpers.logJndiContextException
  ProbeId:1636 Reporter:java.lang.Class@aaac2bca
  
  javax.naming.NamingException: NMSV0610I: A NamingException is
  being thrown from a javax.naming.Context implementation. Details
  follow:
  
  Context implementation: com.ibm.ws.naming.jndicos.CNContextImpl
  
  Context method: lookupExt
  
  Context name: npa9a/clusters/npaa_cluster
  
  Target name: jdbc/NPA_DS_NPAA

  Exception stack trace:

  From \websphere\npa9a2\config\cells\npa9a\clusters\npaa_cluster
  \resources.xml,can find:
     <factories xmi:type="resources.jdbc:DataSource"
  xmi:id="DataSource_1373025906303" name="NPA_DS_NPAA"
  jndiName="jdbc/NPA_DS_NPAA" ...
       <connectionPool xmi:id="ConnectionPool_1373025906305"

  surgeThreshold="-1" surgeCreationInterval="0"
  testConnection="false" testConnectionInterval="0"
  stuckTimerTime="0" stuckTime="0" stuckThreshold="0"/>
  
  Search and check code, sounds like relate to this line of code:
  
  
   if ((gConfigProps.getStuckQueryTime() > 0
  
   && gConfigProps.getStuckQueryInterval() > 0)) { //158708.3 //
  PH48686
  
  
  But from configuration, gConfigProps should not be Null.

  ****************************************************************
  The follow error may occur during serialized processing of a
  datasource connection pool object.
  com.ibm.websphere.naming.CannotInstantiateObjectException:
  Exception occurred while the JNDI NamingManager was processing
  a
  javax.naming.Reference object. [Root exception is
  java.lang.NullPointerException]
  at com.ibm.ws.naming.util.Helpers.processSerializedObjectForLo
  okupExt(Helpers.java:1235)
  at com.ibm.ws.naming.util.Helpers.processSerializedObjectForLo
  okup(Helpers.java:928)
  

Problem conclusion

• The properties that are null from the serialized processing of
  a datasource are now being initialized correctly.
  
  The fix for this APAR is targeted for inclusion in fix pack
  9.0.5.17. For more information, see 'Recommended Updates for
