A DESCRIPTION OF THE PROBLEM :
Opening a SctpServerChannel always fails in Java 13 (also in Java 14 EA). The same operation works fine on Java 12.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run this class:

import com.sun.nio.sctp.SctpServerChannel;

public class SctpBug {

  public static void main(String[] args) {
    try (SctpServerChannel serverChannel = SctpServerChannel.open()) {
      if (serverChannel.isOpen()) {
        System.out.println(" *** SCTP serverChannel is open");
        Thread.sleep(1000);
      }
    }
    catch (Exception e) {
      System.out.println(" unable to load *** SCTP *** :" + e.getMessage());
    }

    System.out.println(" *** SCTP serverChannel is closed");
  }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
 *** SCTP serverChannel is open
 *** SCTP serverChannel is closed

ACTUAL -
Exception in thread "main" java.lang.UnsatisfiedLinkError: 'void sun.nio.ch.sctp.SctpNet.init()'
