NullPointerException if mapper interface has Generic types

[scienty]

@Mapper
public interface IMapper<A, B> {
  public B atob(B bobj);
}

I found this issues on 0.12 version with gradle but I think it is related to the build tool.

Caused by: java.lang.NullPointerException

There is another case where super interface has Generic type and child interface has @Mapper, compilation fails too

e.g

public interface IMapper<A, B> {
public B atob(A aobj, B bobj);
}

@Mapper
public interface MyClassMapper<MyAClass, MyBClass> {
}

error:
error: In type : A and Out type : B differs and this kind of conversion is not supported here
error: In type : B and Out type : A differs and this kind of conversion is not supported here
error: Failed to generate mapping method for type A to B not supported on com.test.IMapper.atob(A,B) !

Can we not reduce the generics first and then generate code?

This should now be fixed for both error cases.

Anyone got this working? I am still getting NullPointer exception on v0.14
