Thanks for develop such a great tool for java native bindings.

However, I have found a issue in W32Service.stopService(). In my scenario, when I use W32Service.stopService() to stop one of my windows services, it throws Unable to stop service exception. Digging into the issue, I find that in my scenario, When Advapi32.INSTANCE.ControlService(handle, Winsvc.SERVICE_CONTROL_STOP, new Winsvc.SERVICE_STATUS()) is called, the dwCurrentState of the service is not changed to SERVICE_STOP_PENDING but still is SERVICE_RUNNING. So, the waitForNonPendingState() will return immediately and queryStatus().dwCurrentState != Winsvc.SERVICE_STOPPED will be true.
Therefore, the Unable to stop service excepiton will be throwed.

My System is Windows 8.1.
