[Java] EchoServer can close socket before client has finished reading

[asfimport]

When the EchoServer finishes running the client connection, the socket is closed immediately. This causes a race condition and the client will fail with a

 SocketException: connection reset 

if it has not read all of the echoed batches.

This was consistently happening with the fix for ARROW-6315
