We didn't know about the JPA spec on this particular detail, thanks for the precision.
Nonetheless, we don't want to override the @MapKeyJoinColumn, we just want the annotation to be taken into consideration while we use @AssociationOverride to override something else. We have updated the test case (https://github.com/florianlacreuse/hibernate-test-case <https://github.com/florianlacreuse/hibernate-test-case>). In Employee entity we use the same embeddable twice, so we have to use @AssociationOverride to name the two join tables. In both tables, the column related to the key has the default name ("experiences_KEY") instead of the one provided by the @MapKeyJoinColumn ("jobtitle_id"). To resume, we understrand that it's not possible to override @MapKeyJoinColumn but @MapKeyJoinColumn should not be ignored. In Employee entity you can also find a third attribute with the same embeddable but without any @AssociationOverride. In this case, @MapKeyJoinColumn works as expected.
