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:
debug:

Answer
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.
