      FULL PRODUCT VERSION :
      java version "1.8.0_25"
      Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
      Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Darwin leitang-MacBook-Pro.local 14.5.0 Darwin Kernel Version 14.5.0: Sun Sep 25 22:07:15 PDT 2016; root:xnu-2782.50.9~1/RELEASE_X86_64 x86_64

      A DESCRIPTION OF THE PROBLEM :
      public static void main(String[] args)
        {
          try {
             String xx = "http://coder_1.tanglei.name";
              java.net.URI u = new java.net.URI(xx);
           System.out.println(u);
           System.out.println(u.getHost()); // null
             java.net.URL url = new java.net.URL(xx);
              System.out.println(url);
           System.out.println(url.getHost()); // coder_1.tanglei.name
              java.net.URI u2 = new java.net.URI(url.getProtocol(), url.getHost(), url.getPath(), "");
             System.out.println(u2);
          } catch (Exception e){
             System.out.println("exception got: " + e.getMessage());
          }
        }


      "_" is not allowed in java.net.URI but is allowed in java.net.URL.

      output:

      http://coder_1.tanglei.name
      null
      http://coder_1.tanglei.name
      coder_1.tanglei.name
      exception got: Illegal character in hostname at index 12: http://coder_1.tanglei.name#
