             Summary: Improve EvaluationContextImpl memory usage
                 Key: DROOLS-2116
                 URL: https://issues.jboss.org/browse/DROOLS-2116
             Project: Drools
          Issue Type: Enhancement
          Components: dmn engine
            Reporter: Fedor Gavrilov
            Assignee: Fedor Gavrilov
            Priority: Minor


Currently java.util.Stack is used to represent call stack. This data structure copies arrays on each pop operation and thus fits the role worse than LinkedList and ArrayDeque offered by standard library, which both offer better performance and less GC pressure.
