[drlvm][reliability] VM crashes on java.net.InetAddress.isReachable()
---------------------------------------------------------------------

                 Key: HARMONY-1830
                 URL: http://issues.apache.org/jira/browse/HARMONY-1830
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Nikolay Bannikov


VM crashes on java.net.InetAddress.isReachable() methods after 300 iterations.
Note, that all works fine on RI.

import java.net.*;

class Test2{
  public static void main(String[] args){
    String[] arr = {"localhost", "localhost", "localhost", "localhost", "localhost", "localhost"};
    for(int j = 0; j < 500; j++) {
      if (j % 10 == 0) {
            System.out.println("Iterations: " + j);
      }
      try{
        for(int i=0; i<arr.length; i++){
          InetAddress inet = InetAddress.getByName(arr[i]);
          inet.isReachable(1000);
          inet = null;
        }
        System.gc();
      }catch(Exception e){
        e.printStackTrace();
      }
    }
  }
}
