Solution

This error can be raised when the Java Virtual Machine does not support the TLS 1.1 protocol, required by Salesforce.

Java version 1.6 and version prior to 1.7.0.71 are generally concerned, some other versions may be concerned too, depending on how they are packaged or configured.

=> Upgrade to the latest Java 7 or Java 8, or enable the missing protocol as described here.

How to check that a java version supports TLS 1.1 :

- Execute a process with a Beanshell Scripting action

import javax.net.ssl.*;
SSLParameters sslParameters;
sslParameters = SSLContext.getDefault().getDefaultSSLParameters();
String varname = "/PROTOCOL ";
String[] vals = sslParameters.getProtocols();
for (String val: vals) {
    __ctx__.publishVariable(varname+val, "OK");
}

- After execution, the view "Session Variables" will show the list of available protocols, "PROTOCOL TLSv1.1" should be listed.
