When I try to use URLConnection to check if a url is accessible using the following code:
try {
URL url = new URL("http://169.254.169.254/latest");
URLConnection connection = url.openConnection();
connection.setConnectTimeout(5000);
connection.connect();
System.out.println("Connected successfully using url");
} catch (IOException e) {
e.printStackTrace();
}
I expected the behavior is: connect should be success if the host is reachable, else throw exception. It works fine without the anti-virus application, but always print “connected successfully” even the host is not reachable.
