IdStory Identity Manager

During removing assigned roles by request. Is created concept for remove identity role. Same identity role is already in removing process by another request (this request is processed). After I create this duplicit concept and identity role is removed by another request. The new concept and request throw exception:

org.springframework.orm.jpa.JpaObjectRetrievalFailureException: Unable to find eu.bcvsolutions.idm.core.model.entity.IdmIdentityRole with id 3ccd6c56-876a-4272-9f77-a57ee03a676b; nested exception is javax.persistence.EntityNotFoundException: Unable to find eu.bcvsolutions.idm.core.model.entity.IdmIdentityRole with id 3ccd6c56-876a-4272-9f77-a57ee03a676b
