Java: Yahoo Finance API: SocketException: Permission denied

Question

So I'm trying to write my first program that pulls data from the web, and since it's a financial program, I decided to use the (allegedly) easy and simple Yahoo! Finance API. I downloaded the API .jar files, and just to be save, I imported the whole lot of them into Eclipse via the Add External Jars tool.

Problem is, whenever I try to run it, I get a SocketException: Permission Denied runtime error.

The code that I'm running is incredibly basic:

Stock stock = YahooFinance.get("ORCL");

That one line of code should get the value of Oracle (ORCL) stock from Yahoo Finance. Instead it throws the exception.

I have tried everything I can think of:

1) I disabled firewalls 2) I double checked my .jar imports 3) I tested running this line as part of a separate Thread (a desperate, blind move but I was reaching at that point).

I have exhausted every possible angle of research that I can think of, and all I've found so far is this: Sending email using JSP

This looks like a very similar problem, so I attempted the solution suggested: adding the line "-Djava.net.preferIPv4Stack=true" to my eclipse.ini file. It seems to have had no effect.

Just in case, I'm pasting the contents of my eclipse.ini file here too, just in case I put it in the wrong spot or something:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20140603-1326
-product
org.eclipse.epp.package.standard.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Djava.net.preferIPv4Stack=true
-Dosgi.requiredJavaVersion=1.7
-Xms40m
-Xmx512m

I'm out of ideas right now. I just want to know why that exception is being thrown, and what I can do to prevent it.

Thanks in advance.

Edit: By request, the full stack trace.

Is this running in an applet or with WebStart or in other kind of sandbox? — Thilo, Apr 28 '15 at 05:49
It's just in Eclipse right now. I wouldn't even call it a program, the entire thing is literally that one line of code, I haven't been able to do anything else because I can't get that working. — craigmiller160, Apr 28 '15 at 11:21

I think I'm having the same problem: sometimes it takes a little bit hard, but I managed to get the information I wanted being a little bit boring, I mean, recursively:

void searchQuote(symbol) throws InterruptedException {
    try{
        Stock stock = YahooFinance.get(symbol);
    }catch(Exception e){
        if(e.getClass().getName().equals("java.net.SocketException") ||
                 e.getClass().getName().equals("java.net.SocketTimeoutException")){
            Thread.sleep(60000);
            searchQuote(symbol);
        }
    }
}

For me, it worked.
