Hi, Quick update to my own post. Using developer logging I was getting messages about JTDS not being present in the classpath. This confused me as there is no reference to JTDS at all that I could find but I did add the jar file to see what happened. With it present I find that the error in the original email is often associated as follows (in terms of timing) but I couldn't say if there is an actual link.

Is JTDS support something that has been added on purpose or have I just managed to misconfigure something? I do have the Microsoft SQL Server and SQL Azure extension installed and this is the only place that I can find JTDS listed. Searching the Geoserver code base this is the only reference to JTDS I've found: https://github.com/geoserver/geoserver/blob/445625cdad44e79c48682b0c9852e1e2586c018e/src/community/release/ext-wps-remote.xml That is not currently installed but I may have installed it on DEV previously so perhaps that plugin has introduced something into my configuration?
