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

             Summary: SumAccumulator should behave according to JPA spec
                 Key: ISPN-5780
                 URL: https://issues.jboss.org/browse/ISPN-5780
             Project: Infinispan
          Issue Type: Bug
          Components: Embedded Querying
    Affects Versions: 8.0.0.Final
            Reporter: Adrian Nistor
            Assignee: Adrian Nistor
             Fix For: 8.1.0.Alpha1


Currently it just preserves the type of the field, which can easily lead to overflow. The JPA spec tries to avoid it by widening the numeric type,  see 10.2.7.4. JPQL Aggregate Functions of JPA spec here: http://docs.oracle.com/cd/E12839_01/apirefs.1111/e13946/ejb3_langref.html
