There seems to be a bug with the ParameterExpressionImpl class when rendering.

If you create a criteria query using a ParameterExpression instance in
multiple places in your query the rendering of this query will produce
multiple pram0, param1, param2 for the same ParameterExpression
instance.

We fixed this bug by augmenting the RenderingContext interface with
generateParameterName(Expression<?> exp). With this information  the
rendering context can give back the same jpaqlParameterName for the
same ParameterExpression instance. All it has to do is do a lookup in
its explicitParamtermapping map.

Thanks
Jean-Claude
