Constructor injection random error under JDK7 #390

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
When using dependency injection, and there is multiple 1 arg constructor, and 
only one mock that can match. Mockito can fail :

org.mockito.exceptions.base.MockitoException: 
Cannot instantiate @InjectMocks field named 'inputParamValidator' of type 
'class com.whatever.api.rest.validation.InputParamValidator'.
You haven't provided the instance at field declaration so I tried to construct 
the instance.
However the constructor or the initialization block threw an exception : null

Additonal info :

constructors with different 1 arg type, but with different visibility.
