Jean-Frederic Clere resolved MODCLUSTER-234.
--------------------------------------------
Resolution: Rejected
ManagementFactory.getOperatingSystemMXBean().getSystemLoadAverage() is not supported on
windows.
So we can't support it.

try:
import java.lang.management.*;
public class SystemLoadAverage {
public static void main(String[] args) {
System.out.println("Load: " +
ManagementFactory.getOperatingSystemMXBean().getSystemLoadAverage());
}
}
It return -1.0 and the java doc says:
"getSystemLoadAverage
double getSystemLoadAverage()
Returns the system load average for the last minute. The system load average is the
sum of the number of runnable entities queued to the available processors and the number
of runnable entities running on the available processors averaged over a period of time.
The way in which the load average is calculated is operating system specific but is
typically a damped time-dependent average.
If the load average is not available, a negative value is returned.
This method is designed to provide a hint about the system load and may be queried
frequently. The load average may be unavailable on some platform where it is expensive to
implement this method.
Returns:
the system load average; or a negative value if not available.
Since:
