How to set TLS Version in Java SOAP API

Question

I am trying to connect to a new org using the Java SOAP API and am getting the following error:

[UnexpectedErrorFault [ApiFault  exceptionCode='UNSUPPORTED_CLIENT'
 exceptionMessage='TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https.'
 extendedErrorDetails='{[0]}'
]
]

Anyone know how I can set the config differently to force TLS 1.1 or 1.2? I am currently making the connection like so:

ConnectorConfig config = new ConnectorConfig();
config.setUsername(creds.username);
config.setPassword(creds.password + creds.securityToken);
config.setProxy("my.proxy.com", 80);
try {
    soapConnection = Connector.newConnection(config);
    metadataConnection = new MetadataConnection(config);
}

Answer 1

The problem here is that although Java 7 and higher support TLS 1.1 and 1.2, they are not enabled by default. You can enable them by using:

System.setProperty(“https.protocols”, “TLSv1,TLSv1.1,TLSv1.2”);

You can also update the java.security file located in JRE_HOME/lib/security/java.security: directory.

Update jdk.tls.disabledAlgorithms property and add TLSv1, TLSv1.1 to reject lower security protocol versions.
