Can an abstract class be mocked using mockito?

In a class under test, if its constructor takes in an abstract class parameter can we mock it using mockito?

Ex

public abstract AbstractClass{
} 

//Class under test
public class SourceClass{            
  SourceClass(AbstractClass abstractClass){}            
}

@RunWith(MockitoJUnitRunner.class
public SourceClassTest{
 @Mock
  AbstractClass abstractClass;
}

whenever I do this i get this error

java.lang.ExceptionInInitializerError

Ther version of mockito I am using i 1.8.5
