Method interception does not work if another thread has access to object in constructor

The unit test below reproduces this behavior:
---------------- GuiceAopTest.java ---------------
public class GuiceAopTest {
@Test
public void testGuiceAop(){
Injector injector = Guice.createInjector(new MyModule());
MyService myService = injector.getInstance(MyService.class);
Assert.assertTrue("myService.isIntercepted() should return true", myService.isIntercepted());
}
}

@Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD)
@interface MyAnnotation {}
class MyModule extends AbstractModule {
@Override
protected void configure() {
bindInterceptor(Matchers.any(), Matchers.annotatedWith(MyAnnotation.class), new MyInterceptor());
}
}

class MyInterceptor implements MethodInterceptor{
@Override
public Object invoke(MethodInvocation invocation) throws Throwable {
return true;
}
}

class MyService{
@Inject
public MyService() {
for(int i=0;i<10;i++){
//this line breaks test
Executors.newCachedThreadPool().execute(()->isIntercepted());
}
}
@MyAnnotation
public boolean isIntercepted(){
return false;
}
}
