William Burns commented on ISPN-8385:
-------------------------------------

Talking with [~gustavonalle] the user can do `cache.getAdvancedCache().getKeyDataConversion().toStorage(key)` to get the underlying key as the storage requires. I will add some documentation to the `DataContainer` to say this shouldn't be used directly and the user should use the above method to convert if the underlying cache isn't stored as is.

> Off-heap container entries contain some additional bytes (ASCII 1,2,1,4), which probably shouldn't be there. Besides additional consumption of memory, it can cause problem as entry put into the cache with cache API is not accessible via container API (which is available to the use), i.e. something like this will fail:
> {noformat}
> cache.put(key, value);
> container = AbstractDelegatingCache.unwrapCache(cache).getAdvancedCache().getDataContainer();
> InternalCacheEntry entry = container.get(key);
> {noformat}
