After 6.2.2, all Java SSL handshakes fail.

Hi I have been trying to troubleshoot a problem I have with filebot on our ReadyNas. At first I thought it was a FileBot thing, but it's not. Ever since I upgraded to 6.2.2, all outbound SSL handshakes are failing from Java.

I have installed/uninstalled/reinstalled (alot) java 1.7 jdk using apt-get. I have googled a heap, and the servers I am trying to connect to for testing do not use self signed certs. Even so I have tried to import them manually. I have uninstalled ca-certificates and ca-certificates-java, I have set the $JAVA_HOME, unset it, left it as default (blank) after apt-get. I'm out of ideas.

Whether running basic FileBot command (filebot -script fn:sysinfo) or using a test class HTTPSClient.java, I get the same error, which is

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I am using HTTPSClient to try to connect to docs.google.com, godaddy.com, microsoft.com, facebook.com, etcetera. Mainstream secure sites.

I am not sure what to do from here, any tips?

The HTTPSClient.java is a class I found while googling, it's contents are as follows:

import java.net.*; import java.io.*; import java.security.*; import javax.net.ssl.*; public class HTTPSClient { public static void main(String[] args) { if (args.length == 0) { System.out.println("Usage: java HTTPSClient host"); return; } int port = 443; // default https port String host = args[0]; try{ Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider()); SSLSocketFactory factory = (SSLSocketFactory) SSLSocketFactory.getDefault(); SSLSocket socket = (SSLSocket) factory.createSocket(host, port); Writer out = new OutputStreamWriter(socket.getOutputStream()); // https requires the full URL in the GET line out.write("GET / HTTP/1.0\\r\\\n"); out.write("\\r\\n"); out.flush(); // read response BufferedReader in = new BufferedReader( new InputStreamReader(socket.getInputStream())); int c; while ((c = in.read()) != -1) { System.out.write(c); } out.close(); in.close(); socket.close(); }catch (IOException e) { System.err.println(e); } } }
