Description

UIMA AS client should detect when its process is terminating and perform necessary cleanup. Applications using UIMA AS client may not call stop() on the UIMA AS client and exit, causing an ugly exception on the broker console. ShutdownHook makes sure that the stop() is always called which closes broker connection.
