Unknown ordinal value [46] for enum class error with Hibernate

I'm developing a Java web App using Hibernate and Spring. I define an Enum as follow: 

public enum FeatureType implements ParentEnumInterface{

    VAL0(0, "VAL0"), VAL1(1, "VAL1"), VAL2(2, "VAL2"), VAL3(3, "VAL3"), VAL4(4, "VAL4"), VAL5(5, "VAL5"),
    ...
    VAL43(43, "VAL43"), VAL44(44, "VAL44"), VAL45(45, "VAL45"), VAL46(46, "VAL46");

    private String translate;
    private FeatureType(int ordinal, String translate)
    {
        this.translate = translate;
        setEnumOrdinal(this, ordinal);
    }

    public String getName()
    {
        return name();
    }

    private static void setEnumOrdinal(Enum object, int ordinal){
        Field field;
        try{
            field = object.getClass().getSuperclass().getDeclaredField("ordinal");
            field.setAccessible(true);
            field.set(object, ordinal);

        }catch(Exception ex){
            throw new RuntimeException("cannot update enum ordinal", ex);
        }
    }
    public String getTranslate()
    {
        return translate;
    }


}

Because I have very featureType and it's possible I delete some of them in developing time, I define ordinal for all featureType.

I use FeatureType Enum in my entity as follow:

public class MetaData implements Serializable{
    @Id
    @GeneratedValue
    private Long Id;

    private FeatureType featureType;

    // Getters And Setters
}

My application works perfectly as long as FeatureType members are less than 46. However, when I add the 47th member, an error occurs as follows:

enter image description here

First let me say something: I belive that it is (let me express it friendly) a not so good idea to manipluate the enum ordinals!

I guess the problem is that you have a gap in the enum ordinals. And you used the ordnials to map them with hibernate. So Hibernate use the OrdinalEnumValueMapper. The code used by this mapper is:

private Enum fromOrdinal(int ordinal) {
    final Enum[] enumsByOrdinal = enumsByOrdinal();
    if ( ordinal < 0 || ordinal >= enumsByOrdinal.length ) {
         throw new IllegalArgumentException(
              String.format("Unknown ordinal value [%s] for enum class [%s]", ordinal,enumClass.getName()));
    }
    return enumsByOrdinal[ordinal];
 }

 private Enum[] enumsByOrdinal() {
      if ( enumsByOrdinal == null ) {
           enumsByOrdinal = enumClass.getEnumConstants();
           ...
      }
      return enumsByOrdinal;
 }

You notice that this code obtain the list of enum values in an array by T[] getEnumConstants() (a method of Class) and then access that array at the position of the ordinal. BUT YOU CHANGE THE ORDINAL, so it will access the wong value. - If you are lucky, it will try to access an index that is not in the array and an exception occures, it you have a bad day it will find have a value at that index, but then it could be the wrong one (because of a gap).

Solution: Remove the ordinal maniulation and use @Enumarated(value=EnumType.STRING) instead
