Indeed. Sorry about that.

Yes, lets' just use this one and https://bugs.openjdk.org/browse/JDK-8304053 as the associated bug to integrate.

On 8u, `src/solaris` is that generic version unless we opt out.

Yep.

Sounds good. The `unix` [copy](https://github.com/openjdk/jdk8u/blob/ebbd3a87b0c473a744499d5f7691e5207cd73186/jdk/src/unix/classes/jdk/internal/platform/SystemMetrics.java) doesn't do anything in 8u. @adamfarley Could you please do that?
