Ciao Tim,
Jody is right, you bypassing GeoServer internal machinery creating
connection pools over and over (not even sure you are dispoing them at
the end...).

To rely on GeoServer internal machinery you can follow this example:
https://github.com/afabiani/geoserver-enterprise/blob/downloadServices-latest/src/extension/wps-download/src/main/java/org/geoserver/wps/gs/DownloadProcess.java#L141

There we are trying to get ahold of the FeatureTypeInfo in GeoServer
for a layer to extract features for a custom download service.
Check the sequence of layer name --> layerInfo --> ResourceInfo

Then, if the ResourceInfo is a FeatureTypeInfo (vector layer) we go to
the right download service:

https://github.com/afabiani/geoserver-enterprise/blob/downloadServices-latest/src/extension/wps-download/src/main/java/org/geoserver/wps/gs/VectorDownload.java#L80

Sorry to be this short but I believe you can get some good indications anyway.

Regards,
Simone Giannecchini
