I have re-tested  [HHH-10857] with Hibernate 5.4.15:

* For “simple” Embeddables (directly used in the Entity as @Embedded), @Convert annotation works.

* For Embeddables in ElementCollections, @Convert annotation also works now. So, the original issue [HHH-10857] seems to be fixed.

* However, in the following situation, @Convert is still ignored:
** I have an Element Collection of an Embeddable OuterEmbeddable.
**  “OuterEmbeddable“ contains another Embeddable called InnerEmeddable
** Within InnerEmeddable I use @Convert on basic fields. But it is ignored.

My current workaround is to use @Convert one level higher:

{code:java}@Embeddable
class OuterEmbeddable{
@Convert(converter = MyConverter.class, attributeName = "theFieldToConvert")
InnerEmeddable theInnerEmbeddable
}{code}

My testcase reveals some more details:

* It works if I enforce field level access on the embeddables by “@Access(AccessType.FIELD)“
* The error occurs (but only on the inner embeddable , as described above ) if I do not enforce field level access.
