I’m using a Embeddable Object to store i18n in a JSONB-Column like this:

@Table(schema = "mdata", name = "PART")
@Audited(withModifiedFlag = true)
public class Part {

   @JdbcTypeCode(SqlTypes.JSON)
   Translation description;
...

with

@Embeddable
public class Translation {
   String de;
   String en;
}

All changes to the Part entity trigger an entry in the envers-table PART_AUD, but

• changes to the JSONB description-column are not marked as modified and the
• jsonb-values in the PART_AUD are always NULL.

I have added a Quarkus Sample-Project with a test-case.

My findings so far:

I use Flyway to create the tables → the _AUD table has a jsonb-column, like the original table.

Without flyway, if i configure the project to let hibernate create the tables, the _AUD table has separate STRING columns for each field in the embeddable! This seems odd…

In the insert-statement that envers generates the jsonb-column is missing at all (see console-log of my test):

    insert 
    into
        base.PART_AUD
        (REVTYPE,description_MOD,name,name_MOD,stamp,stamp_MOD,REV,id) 
    values
        (?,?,?,?,?,?,?,?)
