Docker elastic 6.3 complains about java 9

```auto
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release
Unrecognized VM option 'PrintReferenceGC'

```

When I look at the source code of the [dockerfile on github](https://github.com/elastic/elasticsearch-docker/blob/6.3/templates/Dockerfile.j2), I see references to jdk8 and 10.

1. Do we have a version of ES 6.3 that runs on JDK 1.8?
2. If not then is there a plan to create one?
3. What options do we have if 1.8 is not supported for docker images?

If java 8 is strongly recommended for elasticsearch 6.3 then why is the docker elasticsearch is shipped with java 10 as the default... shouldnt it be java 8?

Anyways... as a workaround, I have created my own docker image using elasticsearch's image and installed java 8 in it.
