Review comment:
```
root@yikun-x86:~# java -XshowSettings:properties -version 2>&1 > /dev/null |
grep 'java.home' | awk '{print $3}'

```
looks like it link to `$JAVA_HOME/jre` in my local env.
Maybe we could just use `/usr/lib/jvm/java-17-openjdk-$(dpkg
--print-architecture)/` or asign `dpkg --print-architecture` to ARCH in
dockerfile.
