Yep, the OpenJDK in Solr image is pure open source, no Oracle license required.
If I’m not mistaken it is the AdoptOpenJdk distro under the hoods, which will receive patches for several years unlike Oracles openjdk distro that is only updated for 6 months. For every Solr release we refresh all docked images with newest JRE 11 version such that even a pull of 8.1 will get latest patched java. We should perhaps document this somewhere. I plan to add some “Solr on Docker” chapter to the reference guide.
