When using the standard DockerFile available here, GraphDB fails to start with the following output:
Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME
Looking into it, the DockerFile uses adoptopenjdk/openjdk11:alpine which was recently updated to Alpine 3.14.
If I switch to an older Docker image (or use adoptopenjdk/openjdk12:alpine) then GraphDB starts without a problem.
How can I fix this while still using the latest version of adoptopenjdk/openjdk11:alpine?
Below is the DockerFile:

The issue comes from an update in the base image. From a few weeks adopt switched to alpine 3.14 which has some issues with older container runtime (runc). The issue can be seen in the release notes: https://wiki.alpinelinux.org/wiki/Release_Notes_for_Alpine_3.14.0
Updating your Docker will fix the issue. However, if you don't wish to update your Docker, there's a workaround.
Some additional info: The cause of the issue is that for some reason containers running in older docker versions and alpine 3.14 seem to have issues with the test flag "-x" so an if [ -x /opt/java/openjdk/bin/java ] returns false, although java is there and is executable.
You can workaround this for now by
if [ ! -x "$JAVA" ]; then echo "Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME" exit 1 fi
Passing it to the Dockerfile is done with 'ADD' You can check the GraphDB free version's Dockerfile for a reference on how to pass the zip file to the Dockerfile https://github.com/Ontotext-AD/graphdb-docker/blob/master/free-edition/Dockerfile
