      Description

      Enums cannot be serialized without transforming them.

      I propose, that all java enums are serialized (and deserialized) using the name() method (or valueOf() method).

      Example (using QueryDSL):

      @Entity
      public enum Type {
      TYPE1, TYPE2
      }

      public class MyObject {

      protected Type type;

      public Type getType() {
      }

      public void setType(Type type)

      { this.type = type; }

      }

      Usage:

      QMyObject.myObject.type.eq(Type.TYPE1); // ends in:

      java.lang.IllegalArgumentException: can't serialize class Type
