----------------------------------------------------------
Hi,

while supporting an app development team, I'm facing a tough TLS issue - maybe you experts have an idea.

They try to open an HTTPS connection to the server URL https://nfe-homologacao.sefazrs.rs.gov.br:443/ws/NfeAutorizacao/NFeAutorizacao.asmx. This is a Web Service of some Brazilian financial authority. So, what I'm basically doing is this:

--code snippet--
URL url = new URL("https://nfe-homologacao.sefazrs.rs.gov.br:443/ws/NfeAutorizacao/NFeAutorizacao.asmx");
HttpsURLConnection con = (HttpsURLConnection)url.openConnection();
con.setHostnameVerifier(new DefaultHostnameVerifier());

// optional default is GET
con.setRequestMethod("GET");

System.out.println("Sending 'GET' request to URL: " + url);
int responseCode = con.getResponseCode();
System.out.println("Response Code: " + responseCode);
--end code snippet-

I expect it to return "403 - not authorized".

The coding will work with JDK7. However, with JDK8, I get this type of exception:

java.net.SocketException: Unrecognized Windows Sockets error: 0: recv failed

        ...

I can get it to work in JDK8 by forcing it to TLSv1 only, e.g. by setting property -Djdk.tls.client.protocols=TLSv1.

For JDK9 I even get a different exception:

I've debugged a lot today and tried to get something out of the javax.net.debug output but I didn't get any further with this - probably due to my lack of understanding the details of TLS communication and its implementation. I know the server is using some legacy protocol but still I think it should work.

Maybe someone has any helpful idea? Is it a bug? You can simply try to run my test code snippet and should see the issue immediately...

Thanks
