Jetty 9 images are broken on linux/amd64 architecture

$ sudo docker pull jetty:9-jdk11
9-jdk11: Pulling from library/jetty
no matching manifest for linux/amd64 in the manifest list entries

Looks like the jetty builds lack manifest information. Also happens with the current 9-jdk8 tag. Do I just need to wait longer (an hour already passed) or is there something broken?
