Can you try executing this code and let me know if it works for you with the
IBM Java?
{code:java}
SSLContext sslContext = SSLContexts.custom()
.useProtocol("SSL_TLSv2")
.build();
CloseableHttpClient httpclient = HttpClients.custom()
.setSSLContext(sslContext)
.build();
try (CloseableHttpResponse response = httpclient.execute(new
HttpGet("https://www.sandbox.paypal.com/";))) {
System.out.println(response.getStatusLine());
EntityUtils.consume(response.getEntity());
}
{code}

> 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
> Labels: tls
> Attachments: ApacheGet.java, FluentGet.java, Get.java
>
>
> A simple client program fails to connect to any site that _requires_ TLSv1.2.
> The attached {{ApacheGet.java}} program, run with
> org.apache.httpcomponents/httpclient version 4.5.2 and 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.
> The similar, simple, {{Get.java}} program that uses the built-in Java
> libraries instead of Apache HttpClient works fine on both IBM Java and Oracle
> Java.
