[THREDDS #PLL-568775]: TDS 5.4 issues

Greetings!

This looks very similar to an issue we just recently fixed (after 5.4 was 
released). That issue was that datasets that had a location specified in ncml 
were not being correctly found. Would you mind trying the latest snapshot to 
see if your problems are solved by that fix?

The snapshot is here:

https://artifacts.unidata.ucar.edu/repository/unidata-snapshots/edu/ucar/tds/5.5-SNAPSHOT/tds-5.5-20220720.145611-7.war

If you still have issues, just let us know and we will have a closer look.

Best,
Tara

================================================================
Im working on an upgrade from tds 4 to tds 5.

We're running the new service on tomcat 9/java 11.

Im new to TDS so theres lots I dont understand but I'm hoping you can 
point me in the right direction on a couple of issue.

I hope these arent too obvious. I have looked through the upgrade guide 
without much success.


Anyway, for one of our datasets which is configured as follows


<?xml version="1.0" encoding="UTF-8"?>
<catalog name = "ANUClimate"
          xmlns = 
"http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0";
          xmlns:xlink = "http://www.w3.org/1999/xlink";>

   <service name="agg" serviceType="Compound" base="">
     <service name="ncdods" serviceType="OPENDAP" base="/thredds/dodsC/" />
     <service name="wms" serviceType="WMS" base="/thredds/wms/" />
     <service name="wcs" serviceType="WCS" base="/thredds/wcs/" />
     <service name="subsetServer" serviceType="NetcdfSubset" 
base="/thredds/ncss/" />
   </service>

   <dataset name="ANUClimate_v2-0_frost_monthly_agg"
            ID="ANUClimate_v2-0_frost_monthly_agg"
            urlPath="gh70/ANUClimate/v2-0/stable/month/frst"
            harvest="true">
     <metadata inherited = "true">

        <documentation xlink:title="NCI Catalogue: Metadata, Licence and

       <documentation type="rights" xlink:title="Licence"

     </metadata>
     <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
       <aggregation dimName="time" type="joinExisting" recheckEvery="60 
min">
         <scan location="/g/data/gh70/ANUClimate/v2-0/stable/month/frst"
               suffix= ".nc"
               subdirs="true" />
       </aggregation>
     </netcdf>
   </dataset>
</catalog>

The WCS service errors out with the following stack trace

java.io.FileNotFoundException:

And the netcdf subset service generates the following error

representation for the target resource or is not willing to disclose
