#Java Hibernate with Negative Enums

I'm using Hibernate for JPA for persisting objects to my database. One class has four possible statuses that I want to represent with an enum, and I want to use a negative status for DELETED for consistency with previous classes:

public enum Status {
  PENDING (0)
  APPROVED(1)
  DECLINED(2)
  DELETED(-1)

  private int numVal;

  Status(int numVal) {
    this.numVal = numVal;
  }
        
  public int getNumVal() {
    return numVal;
  }
}

However, Hibernate doesn't like this and is throwing an exception:

...
Caused by: java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 4
    at [email protected]//org.hibernate.type.descriptor.java.EnumJavaTypeDescriptor.fromOrdinal(EnumJavaTypeDescriptor.java:76)
    at [email protected]//org.hibernate.metamodel.model.convert.internal.OrdinalEnumValueConverter.toDomainValue(OrdinalEnumValueConverter.java:38)
...

Is there a simple way to tell Hibernate to allow the negative Enum value? Or do I have to use non-negative values?

Just make it a user type. If you want Hibernate to use an enum automatically, it will just do the simplest and use their ordinal number.
