Subject [jira] [Updated] (HTTPCLIENT-1784) TLS Client Hello is always TLS 1.0 (0x0301) under IBM Java
Date Wed, 12 Oct 2016 00:35:20 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1784?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bruce Adams updated HTTPCLIENT-1784:
------------------------------------
    Description: 
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.
