我使用了 open-liberty 19.0.0.6 。但是这个应用程序服务器不能在 docker container 上使用 ssl 端口（https）。
收到这个 nullPointerException ：

这是我的 server.xml ：

这是我的 bootstrap.properties 文件：
### Server Configuration ###
default.http.port=8080
default.https.port=9443
default.hostname=localhost
### Database Configuration ###
database.name=logmug
database.hostname=mysql.docker.io
database.port=3306
database.username=root
database.password=rootpass
注意：我的应用程序在 http（端口 80）连接上工作没有任何问题，只有 https（端口 443）有这个问题。
注意：此问题仅在 docker 容器上解决，我在本地机器（外部容器）上测试我的应用程序，所有端口都可以正常工作。
这是应用服务器空指针异常
