Re: [netcdf-java] error trying to create union...

Hello,

Looks like the following problem may have resurfaced using a very recent 
version:








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";  
<http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2%22>;>

<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>
