How do I get a jersey client to use TLSv1.1? I’m trying to force a com.sun.jersey.client.urlconnection.HTTPSProperties (jersey client code eventually goes to this class) to use TLSv1.1 (or TLSv1) to write test code that confirms a server’s protocols. As I setup the client, I do the following:
SSLContext context = SSLContext.getInstance("TLSv1.1");
context.init(null, trustAll, new SecureRandom());
HTTPSProperties props = new HTTPSProperties(hv, context);
clientConfig.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, props);
Inside HTTPSProperties (I downloaded the 1.x source so this may be wrong) I see:
public void setConnection(HttpsURLConnection connection) {
if (hostnameVerifier != null)
connection.setHostnameVerifier(hostnameVerifier);
connection.setSSLSocketFactory(sslContext.getSocketFactory());
}
If I use SSLContext.getInstance("TLS"); instead, the code works fine. I’ve tried add System.setProperty("https.protocols", "TLSv1.1"); but it still doesn’t work. The code above gives the stack trace:

My server (Jetty 9.4.41) thinks it is allowing TLSV1.1. When I dump the sslFactory I get:

Answer
I simplified the question to how do I force a client to use TLSv1.1
I gave up using the jersey client and just used HttpsURLConnection. Turns out using the System.setProperties wasn’t a good ideal but the Diagnostics link from Tasos P. gave me ViewMyClient from SSL Labs.
Code below results in a report that SSL 3, TLS 1.0, and 1.1 are available but TLS 1.2, 1.3 and SSL 2 are not.
// Using these breaks things!
//System.setProperty( "https.protocols", "TLSv1,TLSv1.1" );
//System.setProperty( "jdk.tls.disabledAlgorithms", "SSLv2Hello,SSLv3,TLSv1" );
String requestedProtocol = "TLSv1.1";
testOutput.reportHeader( "SSLLabs " + requestedProtocol );
SSLContext cx = SSLContext.getInstance( requestedProtocol );
cx.init( null, trustAll, new SecureRandom() );
testOutput.report( "Protocol: " + cx.getProtocol() );
testOutput.report( "Provider: " + cx.getProvider().toString() );
StringBuilder sb = new StringBuilder();
javax.net.ssl.SSLParameters p = cx.getSupportedSSLParameters();
sb.append( "Protocols={" );
for( String s : p.getProtocols() ) {
sb.append( s ).append( ',' );
}
sb.append( '}' );
testOutput.report( "SupportedSSLParameters: " + sb.toString() );
testOutput.report( "" );
int read;
byte[] bytes = new byte[1024];
final URL url = new URL(
"https://clienttest.ssllabs.com:8443/ssltest/viewMyClient.html" );
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setSSLSocketFactory( cx.getSocketFactory() );
conn.setHostnameVerifier( hv );
try {
testOutput.report( "Response Message: " + conn.getResponseMessage() );
InputStream in = conn.getInputStream();
File file = new File( filename );
FileOutputStream outputStream = new FileOutputStream( file );
while( (read = in.read(bytes)) != -1 ) {
outputStream.write( bytes, 0, read );
}
outputStream.close();
in.close();
testOutput.report( "File " + filename + " written." );
} catch( Exception ex ) {
testOutput.reportException( ex );
}
