Best practice to verify Optional using hamcrest

This test is not working

assertThat(bundle.getMyObj(), equalTo(Optional.absent()));

---

At the beginning I just use a common object. (Didn't use optional<> yet)

private MyObj myObj;

The test will look like this

assertThat(myBundle.getMyObj(), nullValue());

The I change myObj to

private Optional<MyObj> myObj = Optional.absent();

Then I changed my test to

assertThat(bundle.getTracking(), equalTo(Optional.absent()));

Then I got an error

java.lang.AssertionError: 
Expected: <Optional.absent()>
     but: was <Optional.of(com.my.package.MyObj@2a9627bc)>
Expected :<Optional.absent()>

Actual   :<Optional.of(com.my.package.MyObj@2a9627bc)>

I also try this code below but got compile error

assertThat(myBundle.getMyObj(), equalTo(Optional.of(MyObj)));
