Bruce Adams created HTTPCLIENT-1784:
---------------------------------------
Summary: TLS Client Hello is always TLS 1.0 (0x0301) under IBM Java
Key: HTTPCLIENT-1784
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1784
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Affects Versions: 4.5.2
Environment: IBM Java, many versions including latest Java 8.
Reporter: Bruce Adams
A simple client program fails to connect to any site that _requires_ TLSv1.2.
The Java program below, given the URL https://www.sandbox.paypal.com fails with:
bq. javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
when run on the latest released IBM Java, {{pxa6480sr3fp12-20160919_01(SR3
FP12)}} (available in a Docker image {{ibmcom/ibmjava:8-sdk}}). The same run is
successful on a recent Oracle Java 8.
I similar, simple, Java program that uses the built-in Java libraries instead
of Apache HttpClient works fine on both IBM Java and Oracle Java.
{{ApacheGet.java}}
// Sorry. I didn't figure out how to properly format code in here.
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
class ApacheGet {
public static void main(String args[]) throws Exception {
String urlString = args[0];
HttpGet httpGet = new HttpGet(urlString);
CloseableHttpClient httpClient = HttpClients.createDefault();
try {
CloseableHttpResponse response = httpClient.execute(httpGet);
try {
System.out.println(response.getStatusLine());
} finally {
response.close();
}
} finally {
httpClient.close();
}
}
}
