* if RedisInputStream().read() at Protocol.processBulkReply() returns
-1, it runs with unexpected behavior
* fix: check and if return value is -1, it throws
JedisConnectionException with message "server has closed the connection"
** prevent unexpected behavior, specially ArrayIndexOutOfBoundException
*** calls System.arraycopy() with length = -1 (cause limit = -1) at
RedisInputStream.read()
add pubsub unit test scenario : client-output-buffer-limit exceed
* Redis warns event(disconnect client) to their log, and suddenly
disconnected connection
** http://redis.io/topics/clients -> Output buffers limits
** so test expects JedisConnectionException with proper message
