    Description

      ADDITIONAL SYSTEM INFORMATION :
      Linux 64-bit, Red Hat Enterprise Linux Server release 7.6 (Maipo),

      java -version
      openjdk version "13" 2019-09-17
      OpenJDK Runtime Environment (build 13+33)
      OpenJDK 64-Bit Server VM (build 13+33, mixed mode, sharing)


      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()'
