Eric Milles commented on GROOVY-9922:
-------------------------------------
Since the v8 and the v10 implementations do not use the {{Runtime}} instance,
would it make sense to define this as a static extension method so you could
just call {{Runtime.getPid()}}?
> Add DGM `getPid`

> Sometime we need to know what process id of our running java program, e.g.
> ① shutdown java program via a shell script, e.g. {{kill -15 <pid>}}
> ② attach the current JVM to transform loaded classes on the fly, e.g.
> {{VirtualMachine.attach("<pid>");}}
> {{Runtime.getRuntime().getPid()}} can help us to achieve the goal.
