Review comment:
According to the method annotation, getSystemCpuLoadTicks() method
returns the "recent cpu usage" for the whole system by counting ticks between
the user-provided value from a previous call. If not sleeping, it will always
return value with 0.0D
`
/**
* Returns the "recent cpu usage" for the whole system by counting ticks
from
* {@link #getSystemCpuLoadTicks()} between the user-provided value from
a

*
* @param oldTicks
* A tick array from a previous call to
* {@link #getSystemCpuLoadTicks()}
* @return CPU load between 0 and 1 (100%)
*/
