Verifying a method which returns a char fails

What steps will reproduce the problem?

@RunWith(MockitoJUnitRunner.class)
public class TestClassTest {

    @Mock private TestInterface testInterface;
    @InjectMocks private TestClass testClass;

    @Test
    public void run_test() {
        testClass.runClass();
        verify(testInterface).runInterface();
    }
}

public class TestClass {

    private final TestInterface testInterface;

    public TestClass(TestInterface testInterface) {
        this.testInterface = testInterface;
    }
    public void runClass() {
        testInterface.runInterface();
    }
}

public interface TestInterface {
    char runInterface();
}

What is the expected output? What do you see instead?
The expected output is that the unit test should pass. Instead the following 
exception is thrown:

java.lang.ClassCastException: java.lang.Integer cannot be cast to 
java.lang.Character

What version of the product are you using? On what operating system?
Mockito 1.9.5-rc1
Windows 7 64bit

Please provide any additional information below.
If you change the return type of runInterface() to any other primitive then the 
test passes.
