Quasar multi fibers warning - quasar

Question

I am new to quasar and I tried doing this.
Basically I get a warning the fiber is blocking a thread. Why ? can I not do something like below ?
Thanks
//in my my testclass I have this
String websites[] = {"http://www.google.com",""http://www.lol.com",""http://www.somenoneexistantwebsite.com"};
for(int i=0; i < websites.length ; i++){
TestApp.getWebsiteHTML(websites[i]);
}
//in TestApp
public static void getWebsiteHTML(String webURL) throws IOException, InterruptedException, Exception {
new Fiber<Void>(new SuspendableRunnable() {
#Override
public void run() throws SuspendExecution, InterruptedException {
WebInfo mywi = new WebInfo();
mywi.getHTML(webURL);
}
}).start().join();
}
//in WebInfo
public static String getHTML(String urlToRead) throws Exception {
StringBuilder result = new StringBuilder();
URL url = new URL(urlToRead);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
result.append(line);
}
rd.close();
return result.toString();
}

Have a look at the "Runaway fibers" sub-section in the docs.
HttpURLConnection is thread-blocking so in order to avoid stealing threads from the fiber scheduler for too much time (which risks killing your Quasar-based application's performance) you should rather use an HTTP client integrated with Quasar (or integrate one yourself).
