UIMA AS client needs ShutdownHook to close broker connection
------------------------------------------------------------
Key: UIMA-2065
URL: https://issues.apache.org/jira/browse/UIMA-2065
Project: UIMA
Issue Type: Improvement
Components: Async Scaleout
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Priority: Minor
Fix For: 2.3.1AS
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
at java.net.SocketInputStream.read(SocketInputStream.java:168)
at org.apache.activemq.transport.tcp.TcpBufferedInputStream.fill(TcpBuff
eredInputStream.java:50)

eredInputStream.java:58)

at org.apache.activemq.transport.tcp.TcpTransport.run(TcpTransport.java:
201)
at java.lang.Thread.run(Thread.java:619)
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().
