Callable で割り込みビットを設定すると、Future.get() が呼び出されたときに Callable を表す Future が TimeoutException をスローしないのはなぜですか?
public class ExecutorServiceTest extends MockitoTestCase {
private static CountDownLatch latch1 = new CountDownLatch(1);
class TaskChecksForInterruptedExcAndDoesSetInterruptedBit implements Callable<String> {
@Override
public String call() {
latch1.countDown();
while (!Thread.currentThread().isInterrupted()) {
}
Thread.currentThread().interrupt();
return "blah";
}
}
void testInterrupt() throws Exception {
ExecutorService pool = Executors.newFixedThreadPool(numThreads);
Future<String> future = pool.submit(new TaskChecksForInterruptedExcAndDoesSetInterruptedBit());
latch1.await(); // Don't interrupt the Callable until it actually starts processing
pool.shutdownNow();
try {
future.get(100, TimeUnit.MILLISECONDS);
} catch (final TimeoutException e) {
// Why doesn't this get called!
return;
}
fail();
}
}
