Deploy error for ejb2 remote interface which extends other interface

The scenario is following. The interface marked to define remote interface of bean (e.g. by @Remote annotation) extends other interface. This other interface specifies method which bean has to implement and the children interface (mentioned in bean) does not define any method for implementation.
Deployment on container ends up with following exception:
