PropertyAccessException on Delete and Update Operations for Entities with Enum Fields in JHipster 8.6

Overview of the issue

I encountered a PropertyAccessException when trying to delete or update an entity that includes enum type fields. The error message is: "Could not set value of type [sn.sonatel.dsi.ftsirc.domain.enumeration.Engagement]: 'sn.sonatel.dsi.ftsirc.domain.Projet.engagementBuild' (setter)". The issue does not occur during the creation or reading of the entity, only during delete and update operations. This problem is related to the handling of enum types in entities generated by JHipster version 8.6.

Motivation for or Use Case

This bug is critical as it disrupts the functionality of delete and update operations on entities containing enum type fields, which are essential operations in most applications.

Reproduce the error

Define an entity with multiple enum fields using JHipster version 8.6. An example JDL:

entity Projet {
    numProjet String
    title String required
    statutProjet StatutProjet required
    engagementEtude Engagement
    engagementThink Engagement
    engagementBuild Engagement
}
enum Engagement {
    T1,
    T2,
    T3,
    T4
}

Generate the entity using JHipster.
Attempt to delete or update an instance of this entity via the service layer.
Observe the PropertyAccessException being thrown.

Related issues

After searching the issues, I did not find an exact match for this problem, but it appears to be a potential regression or unintended behavior introduced in version 8.6.

Suggest a Fix

The issue likely stems from how JHipster handles enum types during the generation of entity classes, particularly in the setter methods. A potential fix could involve reviewing and adjusting the handling of enum properties in the generated code.

JHipster Version(s)

The issue occurs in JHipster version 8.6 with java 21
