Using the new Dockerfile, the default path to the static files is missing:
Exception in thread "main" io.javalin.util.JavalinException: Static resource directory with path: '/app/uce.portal/uce.web/target/classes/public' does not exist.
We should update this to load the files from the JAR when building the "release" version.
Hotfix if you need to get it working for now: Update the Dockerfile to copy not only the JAR from "target":
COPY --from=builder /app/uce.portal/uce.web/target /app/uce.portal/uce.web/target
