Unsupported record version SSLv2Hello using CloseableHttpClient
I am trying to make an https call and getting the following error: Unsupported record version SSLv2Hello
Can anyone please shed some light on what I'm doing wrong? Thanks for your help.
Here is the StackTrace:

It seems the problem is that JDK8 clients cannot connect to SSL2 server with the default Provider (SSLv2 is deprecated for a long time). You have to force the server to use SSL3 (or another safer protocol) or you have to use another provider (BouncyCastle?). Currently we have a similar problem with SOAP webservice JDK8 client and JDK6 server.
http://en.wikipedia.org/wiki/Transport_Layer_Security#SSL_2.0
http://tools.ietf.org/html/rfc6176
It looks like you're connecting to a server that incredibly enough in this day and age still supports SSLv2.
Try removing SSlv2ClientHello from the list of enabled protocols, however you do that with Apache HTTPClient.
NB You haven't needed that stuff with the com.sun.net.ssl.internal.ssl.Provider since 2004, and you need to be aware that your TrustManager and HostnameVerifier are both radically insecure. Also TrustManager.getAcceptedIssuers() is not permitted to return null: see the Javadoc.
Figured it out. The two places I tripped over my shoelaces were:
Needed to register https with the PoolingHttpClientConnectionManager Set TLSv1 as the only supported protocol in the SSLConnectionSocketFactorypackage httpcomponents;
