Spring Integration 2.1 to 2.2 Migration Guide

###spring-integration-remote Session Interface

The interface is used by FTP and SFTP modules; in 2.2 a new method was added

String[] listNames(String path);

This method was introduced in 2.1.1 on a temporary sub-interface

ExtendedSession<F>

to avoid breaking any user implementations.

This interface has now been removed and the method moved to

Session<F>

Any user Session implementations must implement this method, to return a simple array of Strings, containing the file names matched to the path. This method is used by the mget command.

###TCP Default Socket Timeout

Previously, when using a client connection factory with both outbound and inbound adapters, sockets created by that factory would get a default socket timeout of 10 seconds. This could be overridden by specifying a large timeout (2.0) or 0 (2.1).

In 2.2 and above, these sockets now get a default timeout of 0 (infinity). If you wish to restore the previous behavior, explicitly set the so-timeout attribute to 10000.

Note that single-use sockets created by a server connection factory continue to be configured with the default of 10 seconds if the so-timeout attribute is not configured.
