OutOfMemoryError in entry retriever when state transfer chunk size is Integer.MAX_VALUE

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).
