assignment to computed value misinterpreted in JDQL UPDATE when entity identification variable is ommitted

[njr-11]

When the optional entity identification variable is omitted (for consistency with JDQL) of a JPQL query such as the following,

UPDATE Coordinate SET x = :newX, y = y / :yDivisor WHERE id = :id

EcilpseLink complains that "The left expression is not an arithmetic expression" instead of interpreting the assignment operation correctly.
