Following tests fails with DB2 because hibernate generates wrong query. It's missing casting of parameters in case expression part of query

org.hibernate.jpa.test.criteria.selectcase.SelectCaseTest.selectCaseWithCastedTypeValuesShouldWork
org.hibernate.jpa.test.criteria.selectcase.SelectCaseTest.selectCaseWithValuesShouldWork
org.hibernate.jpa.test.criteria.selectcase.SelectCaseTest.simpleSelectCaseWithCastedTypeValuesShouldWork
org.hibernate.jpa.test.criteria.selectcase.SelectCaseTest.simpleSelectCaseWithValuesShouldWork
org.hibernate.jpa.test.criteria.selectcase.GroupBySelectCaseTest.selectCaseInOrderByAndSelectExpression
org.hibernate.query.criteria.internal.expression.SearchedCaseExpressionTest.testEqualClause

Example from: SelectCaseTest.selectCaseWithValuesShouldWork
generated query is:

15:14:28,210 DEBUG SQL:94 - 
    select
        selectcase0_.id as id1_0_,
        selectcase0_.value as value2_0_ 
    from
        entity selectcase0_ 
    where
        cast(selectcase0_.value as varchar(255))=case 
            when 1=1 then ? 
            else ? 
        end

but it probably should be

15:14:28,210 DEBUG SQL:94 - 
    select
        selectcase0_.id as id1_0_,
        selectcase0_.value as value2_0_ 
    from
        entity selectcase0_ 
    where
        cast(selectcase0_.value as varchar(255))=case 
            when 1=1 then cast(? as varchar(255)) 
            else cast(? as varchar(255)) 
        end
