[infinispan-issues] [JBoss JIRA] (ISPN-5780) SumAccumulator should behave according to JPA spec

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.Alpha2, 8.1.0.Final, 8.0.2.Final 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
