I want to remove CacheLineTable, by inlining it into UtilCache. This needs to be done to make certain stats get updated correctly, and to support placing things into memory when they get read from the backing disk store.
Of course, removing this class could break external users who may be accessing it. I consider CacheLineTable, and the CacheLine classes, to be internal, and that all access should only be thru UtilCache. As such, any method that currently accesses one of those classes will be deprecated, and throw UnsupportedOperationException, going forward. (I'm aware that webtools calls CacheLineTable.getKeyFromMemory(); that method will still be available, but on UtilCache)
