I suppose the impact of #2 above could be minimised by: * Keeping EvictionPolicyConfig but marking it as deprecated * EvictionRegionConfig could issue a warning if an EvictionPolicyConfig is used, and copy all values across from here to an EvictionAlgorithmConfig * Use a default EvictionPolicyClassName if none is specified (default: SimpleEvictionPolicy that just does Cache.evict()?)
