NetCDF Aggregation Exception

THREDDS:

I've adjusted the CDL in the NetCDF files of interest so that the time
is the slowest varying dimension.  And I have started small (with 6
instead of 6000) files.

Watching the logs I made sure there wer no errors/warnings associated
with this dataset entry:
When I goto the OPeNDAP Service link on this page:
http://nomads.ncdc.noaa.gov:8085/thredds/testDatasets.html?dataset=test/BOWdailyagg2
The following Java exception appears in threddsServlet.log:

===========================================================================
  <dataset name="Blended Ocean Winds Test Daily Aggregation II"
      ID="test/BOWdailyagg2" urlPath="test/BOWdailyagg2" dataType="Grid" >
    <access serviceName="allTest" urlPath="test/BOWdailyagg2"
        dataFormat="netcdf" />

    <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
     <aggregation dimName="time" type="joinExisting">
       <variableAgg name="wind" />
       <scan dateFormatMark="#yyyyMMdd" location="/raid/seawind-test/"

     </aggregation>
    </netcdf>

What am I doing wrong?
Is this more likely a problem with the configuration file or with the
data files?
