Looking at the docker container itself there is a __cacert_entrypoint.sh which takes any traditional certificates mounted at /certificates/* merges them with the image ca-certficates and then uses the right tools to update the JRE cacert store as long as the USE_SYSTEM_CA_CERTS environment variable is set.

So the entry-point script would either need to copy that behaviour or just call that entrypoint script first
