"SSH-2.0-OpenSSH_5.3" is the return message the server sends to the slave when it attempts to handshake. It's part of the error message because it's unexpected, and to give you an idea what's going on.
For some reason, on the port the node tries to connect to, an SSH Server is running. It's not the internal Jenkins SSH server, it'd send 'SSH-2.0-SSHD-CORE-0.8.0' instead (on 1.509.2). Are other slaves able to connect? What happens when you change the TCP port for JNLP slaves?
