- TODO: beware of large images (see Images are larger in JDK 11 coobird/thumbnailator#156)
- TODO: Use

- update GitHub actions (see https://github.com/actions/setup-java/blob/main/docs/advanced-usage.md#adopt)
- consider removing
jdk8maven profile - consider updating postgresql from
9.4.1212.jre7version - consider replacing
