GraphDB Docker Container Fails to Run: adoptopenjdk/openjdk12:alpine - graphdb

Question

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:
FROM adoptopenjdk/openjdk11:alpine

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
Pull the GraphDB distribution
Unzip it
Open "setvars.in.sh" in the bin folder
Find and remove the if block around line 32
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
Zip it again and provide it in the Dockerfile without pulling it from maven.ontotext.com
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
