Is the != check thread safe?

Question

I know that compound operations such as i++ are not thread safe as they involve multiple operations.

But is checking the reference with itself a t

Answer 1

Proved with test-ng:

public class MyTest {

  private static Integer count=1;

  @Test(threadPoolSize = 1000, invocationCount=10000)
  public void test(){
    count = new Integer(new Random().nextInt());
    Assert.assertFalse(count != count);
  }

}

I have 2 fails on 10 000 invocations. So NO, it is NOT thread safe
