Paul,
Sorry that you are seeing this issue. I could not replicate the issue at my end with a simple maven web project.
Can you please give us some more details?
1. Does the project have any other dependencies? It might be possible that this particular jar is also part of another dependency whose scope is not provided.
2. Can you please check if the issue persists with a newly created simple maven web project to rule out project specific issues?
3. If you are still seeing issues, please send us the project along with the pom.xml to help us replicate the issue at our end.
Let us know how it works for you.
