Description

If an application exits without calling stop method on the UIMA AS client, an ugly exception is thrown by the broker:
java.net.SocketException: Connection reset

eredInputStream.java:50)

This exception is thrown by the broker when it realizes that the socket connection to a client closed unexpectedly. Add a Shutdown Hook to the client to enable cleanup even though the application exits without calling stop().
