        ec = phdr.getEvictionAttributes().createEvictionController(null, phdr.getOffHeap());
    } else {
        throw new IllegalStateException("expected LocalRegion or PlaceHolderDiskRegion");
    }

        ((MemLRUCapacityController) ec).setEntryOverHead(getEntryOverHead());
    }
    if (ea.isLRUHeap()) {
        ((HeapLRUCapacityController) ec).setEntryOverHead(getEntryOverHead());
    }
    _setCCHelper(getHelper(ec));
    /*
     * modification for LIFO Logic incubation
     * 
     */
