BasicModel.hasRole mistakenly invokes inheritPrivledges on Identities that do NOT have the role. This causes two issues:

• Privledges are not inherited for identities that have the role.
• Worse when attempting to inherit privledges for identities that do not possess the role and 15 second delay will be occur.

Code in question:
boolean hasRole = !query.getResultList().isEmpty();

if (!hasRole)

{ return relationshipManager.inheritsPrivileges(assignee, role); }

The conditional with bang sign (NOT) should have it removed.
