"Another ORA-00907: missing right parenthesis" bug with Oracle

I'm using JBoss 4.2.1GA, with the Hibernate environment described above, using Oracle 10g, and attempting to perform a query.

I've been receiving a "ORA-00907: missing right parenthesis" error when attempting to perform the query.

Now a similar bug had this down to Hibernate using the 'as' keyword in the query, aliasing the table name - something that has been fixed in Hibernate 3.3.0ga.
(Aliasing a table in the SQL spec is optional, Oracle doesn't support it)

But I still get the same error. The query still contains the 'as' keyword (but not aliasing a table)

Here is an example:

I have two tables. CSIUsers and CSIUserSurveys.

There is a one-to-many mapping between CSIUsers to CSIUserSurveys.

Query query = entityManager.createQuery("FROM " + CSIUser.class.getSimpleName()
+ " cu LEFT JOIN cu.csiUserSurveys us"
+ " WHERE NOT EXISTS (SELECT us FROM cu.csiUserSurveys us WHERE us.csiUserId = cu.csiUserId)");

Result:
