Could you post a bigger part of the stack trace (at least everything
that has org.apache.cayenne in it)?
From what I can see, this is related to in-memory evaluation of the
qualifier. If that's a to-one relationship based on FK, intuitively
this should work, but it probably hits a limitation on in-memory
evaluation.

I am currently trying to use ObjEntity Inheritance in my project, but
I am running into some difficulties. I was hoping that I could use
"someRelationship != null" as the qualifier, but I get the following
error when trying to run the code:
org.apache.cayenne.exp.ExpressionException: [v.3.0-SNAPSHOT Aug 01

Am I doing something wrong here, or did I find a bug?
