i try to use this in win 10 with jdk 1.8、java-thread-affinity v3.2.3，the pc is 4 core with 8 thread. code like this: ExecutorService ES = Executors.newFixedThreadPool(4, new AffinityThreadFactory("bg", AffinityStrategies.ANY)); System.out.println("\nThe assignment of CPUs is\n" + AffinityLock.dumpLocks()); return ES;

and console log is : The assignment of CPUs is 0: CPU not available 1: Reserved for this application 2: Reserved for this application 3: Reserved for this application 4: Reserved for this application 5: Reserved for this application 6: Reserved for this application 7: Reserved for this application

does this mean bind fail?

when run code to cal, got error: 09:17:28.174 [bg] INFO n.o.a.AffinityLock - [bind,314] - Assigning cpu 7 to Thread[bg,5,main] on thread id 9540 09:17:28.175 [bg-2] INFO n.o.a.AffinityLock -

This problem has been solved, because JNA is used in other places in my project, but the version is not 4.4.0, and the version conflicts. Just change the whole project to 4.4.0.
