java - MessagePack and Immutable Objects -

i have many immutable domain objects private final fields , public getter methods. possible serialize them using messagepack implementation java?

i know @message annotation supports public fields, hoping use @messagepackbeans , @ordinalenum annotations. when try , serialize 1 of objects, don't exception on .write call, serialization fails. i've included complete example below.

is there doing wrong, or should give on trying use messagepack?

import java.io.ioexception; import org.msgpack.messagepack; import org.msgpack.annotation.messagepackbeans; import org.msgpack.annotation.ordinalenum;  public class msgpacktest {    @ordinalenum   public static enum myenum {     a;   }    @messagepackbeans   public final static class myobject {     private final string mystring;     private final myenum myenum;      public myobject(string mystring, myenum myenum) {       this.mystring = mystring;       this.myenum = myenum;     }     public string getmystring() {       return mystring;     }            public myenum getmyenum() {       return myenum;     }   }    public static void main(string[] args) {     final myobject obj = new myobject("abc", myenum.a);     final messagepack msgpack = new messagepack();     try {       final byte[] bytes = msgpack.write(obj); //bytes = [-112]       myobject result = msgpack.read(bytes, myobject.class);       //unreachable code - messagetypeexception thrown       system.out.println("success: " + result);     } catch (ioexception e) {       e.printstacktrace();     }   } }
