A DESCRIPTION OF THE PROBLEM :
When bind a socket failed, for example, "java.net.BindException: Address already in use". I expect the jvm not open a file descriptor. But it does open a file descriptor.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the source code below, and run it.
2. Identify the java process id.
3. Use `lsof` to see the opened files of the java program.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No record of the socket file descriptor.
ACTUAL -
Has an record of the socket file descriptor.

---------- BEGIN SOURCE ----------
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;

public class Main {
    public static void main(String[] args) throws Exception {
        Socket s = new Socket();
        // bind an already in use port.
        SocketAddress addr = new InetSocketAddress("127.0.0.1", 6010);
        try {
            s.bind(addr);
        } catch (Exception e) {
            e.printStackTrace();
        }
        Thread.sleep(Long.MAX_VALUE);
    }
}
