Mockito Bug in Spring 2.0.0.RELEASE

I updated my project with the latest revision of Spring (2.0.0.RELEASE) and while my tests worked in 2.0.0.RC1, now it doesn't work and it keeps giving me this error : 

org.mockito.exceptions.base.MockitoException: 
Cannot instantiate @InjectMocks field named 'service'! Cause: the type 'PersonService' is an interface.
You haven't provided the instance at field declaration so I tried to construct the instance.
Examples of correct usage of @InjectMocks:
   @InjectMocks Service service = new Service();
   @InjectMocks Service service;
   //and... don't forget about some @Mocks for injection :)

Here I made a minimal project where you can change the version in the pom file to see it succeed on 2.0.0.RC1 and fail in 2.0.0.RELEASE.

For the a full minimal test - please turn to gituhub.

From the documentation for the @InjectMocks

Mockito cannot instantiate inner classes, local classes, abstract classes and of course interfaces.

In your case you should use inside your test:

@InjectMocks
private PersonServiceImpl underTest;

I have checked in your sample from github, if you change to the implementation of service - tests will be passed
