More Hibernate validation issues

I am using Hibernate with Spring and received some validation errors that I believe are incorrect. In the code snippit below, I receive a type mismatch on current_date() saying that java.util.Date type is expected. However, current_date() should fulfill this type. The second and third errors I am receiving are that IDEA can not resolve the two query parameters in the setParameterList method calls even thou they are defined in the query. Before I submitted these as bugs, I would like to get some input.

Thanks,
Steve

I String HQL =
