I create a simple function which selects all the rows in a table. I then create a Native query which calls this function, setting the resultClass to the entity that maps to the result of the function. When run, Eclipselink fails with the following error:
Exception Description: The primary key read from the row [ArrayRecord(
=> (2,bar,1))] during the execution of the query was detected to be null. Primary keys must not contain null.
Query: ReadAllQuery(name="relationship.getAll" referenceClass=Relationship sql="select r from test.get_relationships() as r")
Attached is a complete test case for this problem.

Here is the result of running the test with log level FINEST. As you can verify from the test case's persistence.xml, the property is set to true:
<property name="eclipselink.jdbc.uppercase-columns" value="true"/>

Executing a native SQL query with a class, requires that the native query returns a result set that matches what the class requires.
The native query you are executing does not appear to return a matching result set.
From the error the row returned is,
ArrayRecord(
=> (1,foo,2))
Which seems to be a result with no column name at all, and the value is some kind of array structure.
What you need to be returned, to be able to map it is,
ArrayRecord(
ID => 1, NAME='foo', inverse=2)
Try something like,
select r.id as ID, r.name as NAME, r.inverse as inverse from test.get_relationships() as r
You could also try executing the SQL through an SQL tool, or with the class and a Map result to see exactly what it returns.
