Provide Externalizers for (Double|Long|Int)SummaryStatistics ------------------------------------------------------------ Key: ISPN-6191 URL: https://issues.jboss.org/browse/ISPN-6191 Project: Infinispan Issue Type: Enhancement Reporter: William Burns Assignee: William Burns Fix For: 8.2.0.Beta2, 8.2.0.Final, 8.1.2.Final The summary statistics classes are used directly by the new streams. Unfortunately they aren't Serializable by default, which can cause issues when using these methods in a distributed cache. The summaryStatistics methods on the (Double|Long|Int)Stream use a hack of forcing an iterator to get these results, but this cannot be applied with the Collectors methods.
