JAVA_OPTIONS with arguments value containing space

How are we supposed to path an argument with a space?

```shell
docker run -e JAVA_OPTIONS="-Xmx1g -Dldap.user=dada" jetty:10

2023-06-28 09:06:48.887:INFO :oejs.Server:main: jetty-10.0.15; built: 2023-04-11T17:25:14.480Z;
```

```shell
docker run -e JAVA_OPTIONS="-Xmx1g -Dldap.user=\"dadaada\"" jetty:10

2023-06-28 09:09:53.305:INFO :oejs.Server:main: jetty-10.0.15; built: 2023-04-11T17:25:14.480Z;

```

```shell
docker run -e JAVA_OPTIONS="-Xmx1g -Dldap.user=\"dada ada\"" jetty:10
