Dan Berindei commented on ISPN-5027:
------------------------------------

We could validate the state transfer chunk size to be <= 10k, there's no reason to have a higher limit in practice.

> {{DistributedEntryRetriever}} pre-allocates an {{ArrayDeque}} and and {{ArrayBlockingQueue}} of the same size as the state transfer chunk size.
> {{ReplStateTransferCacheLoaderTest}} sets the state transfer chunk size to {{Integer.MAX_VALUE}}, so it will trigger an {{OutOfMemoryError}} at the end of the test, when {{TestingUtil.killCaches()}} tries to log the contents of the cache (if TRACE logging is enabled).
