-------------------------------------

This recently caught me out too.  Is there a plan to generate a more meaningful error?

>             Project: Hibernate3
>          Issue Type: Bug
>          Components: query-hql
>    Affects Versions: 3.1
>         Environment: Linux, jdk 1.5, Hibernate 3.1, Oracle 10g

> A query like the one
>     from Dispo.Hibernate.Test.A as a where a.ptrB.ptrC.Oid >= :oid
> leads to a NullPointerException when using Hibernate 3.1. The same query runs without a problem against Hibernate 3.0.5.
> When breaking down the where clause to "a.ptrB.Oid = ptrC.Oid and ptrC.Oid = :oid" the query works.
> The stack trace is:
