Changes between 4.0.2 and 4.0.3

This is a maintenance release that includes a bug fix on connection creation and a bug fix in the NIO mode. This release is backward-compatible with 4.0.2.

Handle TimeoutException on connection creation

When several addresses are provided to the ConnectionFactory and when an address throws a TimeoutException on connection creation, the client wouldn't try the next addresses and throw an exception. Now the client tries to connect to the next address even on a TimeoutException.

Close SocketChannel correctly in NIO mode

The SocketChannel wasn't properly closed in NIO mode. The connections would show up a few dozens of seconds in the management web UI before being closed automatically by the server.
