无法使用部署在 Heroku 上的 Java 应用程序中的 svnkit 连接到 HTTPS svn 服务器

Question

I am using the svnkit to get some information about our svn repository. I used the examples mentioned in the svnkit documentation and I was able to fetch the details when I run the example in my local eclipse. Our repository is accessible via https protocol.

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.*;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.*;
import org.tmatesoft.svn.core.SVNDirEntry;
import org.tmatesoft.svn.core.SVNException;
import org.tmatesoft.svn.core.SVNNodeKind;  
import org.tmatesoft.svn.core.SVNURL;
import org.tmatesoft.svn.core.auth.ISVNAuthenticationManager; 
import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory;
import org.tmatesoft.svn.core.internal.io.fs.FSRepositoryFactory;
import org.tmatesoft.svn.core.internal.io.svn.SVNRepositoryFactoryImpl;
import org.tmatesoft.svn.core.io.SVNRepository;
import org.tmatesoft.svn.core.io.SVNRepositoryFactory;
import org.tmatesoft.svn.core.wc.SVNWCUtil;

public class HelloWorld extends HttpServlet {
public static String abc="";

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
        throws ServletException, IOException {
    resp.getWriter().print("Hello from Java! The repository UUID is \n"+ abc);
}

public static void main(String[] args) throws Exception{
    Server server = new Server(Integer.valueOf(System.getenv("PORT")));
    ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
    context.setContextPath("/");
    server.setHandler(context);
    context.addServlet(new ServletHolder(new HelloWorld()),"/*");

    //If I use these set I am able to fetch the details from SVN.
//String url = "http://svn.svnkit.com/repos/svnkit/trunk/doc";
  //  String name = "anonymous";
    //String password = "anonymous";

    String url = "https://svn.ourComplanyRepo";
    String name = "username";
    String password = "password";
    long startRevision = 0;
    long endRevision = -1;
DAVRepositoryFactory.setup();
SVNRepository repository = null;
repository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url));
ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager(name, password);
    repository.setAuthenticationManager(authManager);
    SVNURL XYZ =  repository.getLocation();
    abc = repository.getRepositoryUUID(true); 
    server.start();
    server.join();      
}

}

WHen I deployed my code to the heroku, I am running into an issue. When I check the heroku logs this the issue that I found

 0m Exception in thread "main" org.tmatesoft.svn.core.SVNException: svn: E175002: connection refused by the server

Could you please help me on how to resolve this?

A Google-search for the error yields some promising leads, try running with:

-Dsvnkit.http.sslProtocols="SSLv3"

... as suggested here .
