JPQL SELECT NEW not joining nor recognising ElementCollection as a collection type

[Riva-Tholoor-Philip]

EclipseLink is rejecting JPQL SELECT NEW clauses where an entity contains an attribute that is an ElementCollection.

For example, SELECT o.comments FROM Rating o WHERE o.id = :id where the column comments is an ElementCollection is correctly returned as a result set.
We can see from the SQL generated by EclipseLink that a JOIN is required to get the data from the Rating_COMMENTS table:

SELECT t1.COMMENTS 
FROM RATING t0 
  LEFT OUTER JOIN Rating_COMMENTS t1 
  ON (t1.Rating_ID = t0.ID) 
WHERE (t0.ID = ?)

However, when we try to use o.comments in a SELECT NEW query like the one below:

SELECT NEW 
  io.openliberty.jpa.data.tests.models.Rating( o.id, o.item, o.numStars, o.reviewer, o.comments )
FROM Rating o 
WHERE o.id = :id

The following error is thrown:

Exception [EclipseLink-0] (Eclipse Persistence Services - 5.0.0.v202408071314-43356e84b79e71022b1656a5462b0a72d70787a4): org.eclipse.persistence.exceptions.JPQLException

I would have expected EclipseLink to be able to satisfy this JPQL query with a SQL Query something like:

SELECT t0.ID, t0.NAME, t0.PRICE, t0.NUMSTARS, t0.EMAIL, t0.FIRSTNAME, t0.LASTNAME, t1.COMMENTS 
FROM RATING t0
  LEFT OUTER JOIN Rating_COMMENTS t1 
  ON (t1.Rating_ID = t0.ID) 
WHERE (t0ID = ?)
