You can also use the $JAVA_HOME environment variable for that which is set when the container is started:

openhab/openhab-docker/blob/0cb2ae5e42488738413e25fa658007ca4feaef42/debian/entrypoint#L7-L13


      
          export JAVA_HOME=$(ls -d /usr/lib/jvm/*jdk* | tail -n 1)
          
          # Configure Java unlimited strength cryptography
          if [ "${CRYPTO_POLICY}" = "unlimited" ]; then
            echo "Configuring Java unlimited strength cryptography policy..."
            sed -i 's/^crypto.policy=limited/crypto.policy=unlimited/' "${JAVA_HOME}/conf/security/java.security"
          fi

Then your changes will keep working with any Java version on any architecture and also when another JVM is used.

The JVM in the container was changed to fix issues on some platforms.
