Hi,

I can get the failure from toolsUI-4.2 using the following NcML:

<?xml version="1.0" encoding="UTF-8"?>

<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>

<attribute name="title" type="string" value="Union"/>

<aggregation type="union">
<netcdf location="MYD021KM.A2011331.0400.005.2011332201942.hdf"/>
<netcdf location="MYD03.A2011331.0400.005.2011332200801.hdf"/>
</aggregation>

</netcdf>

I'm trying to create a union aggregation between two files.
