The JDK version used for building the Bio-Formats Docker image in the OME CI infrastructure is defined in https://github.com/ome/bio-formats-build/blob/master/Dockerfile#L1 and curently uses 8 as the minimal supported Java LTS version.
This commit allows to switch daily between LTS Java versions to increase our testing coverage. Currently the builds alternates between the supported 8 and 11 versions with 17 being a mid-term target.
In addition a first steps pulls the latest verison of the base image which should allow to avoid issues such as ome/bio-formats-build#241 (comment)
