Hello, Looking at: - https://issues.apache.org/jira/browse/HTTPCLIENT-1119
1/ It is not clear for me how the fix works if commit association is correct: - https://fisheye6.atlassian.com/changelog/httpcomponents?cs=1544769 Is the fix about replacing: final SSLSocket sock = (SSLSocket) this.socketfactory.createSocket(); with : SocketFactory.getDefault().createSocket(); 2/ Is the fix only for Java 7 or does it work on Java 8? 3/ Also wondering, I see only SSLConnectionSocketFactory is concerned by fix, so I suppose that SSLSocketFactory was not fixed ? So I suppose that upgrading to HC4.5.1 from HC4.2.3 will not fix the issue unless SSLSocketFactory is used instead of SSLConnectionSocketFactory -- Cordialement. Philippe Mouawad.
