Fixed version (ground truth):

    if (eid != null) {
      dso=(DSpaceObject)IdentifierService.getResource(context,eid);
    }
    if (dso != null && dso instanceof Community) {
      collections=Collection.findAuthorized(context,((Community)dso),Constants.ADD);
    }
 else {
      collections=Collection.findAuthorized(context,null,Constants.ADD);
    }
