[netCDFJava #NNB-487385]: NcML aggregation code fails after recent Java NetCDF library upgrade

Hi Tommy,

I'm assuming that you are running a 4.3 release of the TDS, since you've 
mentioned updating jar files.  I can take a look at the failure if you follow 
these steps to get a clean set of logs that capture the problem:

Stop the tomcat server.
Install the latest release if needed.
Remove/copy all files from {tomcat}/logs and {tomcat}/content/thredds/logs
Restart the server
Make the problem happen
Zip up everything in {tomcat}/logs and {tomcat}/content/thredds/logs.
Send the logs and a detailed description of what you do to make the problem 
happen, and what the problem looks like. If it took a while to get the problem 
to happen, note what time it happened so that we can correlate with the logs.

Thanks,
