Create Java 11 Docker Images

[saw303]

Sonatype provides Docker images running on Java 11 instead of Java 8. Java 11 is much more Docker-aware than Java 8 (JVM 8 is actually completely container unaware). It would be nice to have Java 11 ARM images.

Ooh thanks for the heads-up - this'd certainly make memory limit more flexible.

I need to do more research - sounds like there are a couple of container-specific memory options we can include into cmdline.

But I'm not sure which ones to use, and how they interact with the default -Xms and -Xmx settings...

If you (or anyone) have any idea I'd love to hear from you!

Notes:

• Some memory config examples + params from Nexus system requirement
• java -X 2>&1|less - mem help
• Mem limit "function" - Max memory = [-Xmx] + [-XX:MaxPermSize] + number_of_threads * [-Xss]
• Java memory model

Simply take a look at this fork. As far as I understand, all the important upgrade cases are included. Maybe it makes sense to reintegrate the fork?

Thanks for the link @saw303 , that's helpful.

I'll get round to updating it to Java 17 (or whatever the latest supported version), which will also resolve #31 .
