This same technique works when coded in C language, so I think it must be something different in the way JNA handles it.

HANDLE htimer = kernel32.CreateWaitableTimer(null, true, "MyWaitableTimer"); boolean setTimerResult = kernel32.SetWaitableTimer(htimer, pDueTime, 0L,null, null, true); int waitResult = kernel32.WaitForSingleObject(htimer,Integer.MAX_VALUE);

The last line, above, appropriately blocks execution, even in the JNA version, then continues after the timer fires, when the machine is awake. The difference is that if the machine is sleeping, only the C version wakes the machine when the timer fires, the JNA version does not.

Anybody have any clues, or am I outta luck?
