             Summary: Use Collection instead of Set
                 Key: ISPN-6935
                 URL: https://issues.jboss.org/browse/ISPN-6935
             Project: Infinispan
          Issue Type: Sub-task
          Components: Core
    Affects Versions: 9.0.0.Alpha4
            Reporter: Radim Vansa
            Assignee: Radim Vansa


Currently the xManyCommand commands hold the keys in a set internally. During marshalling and splitting the set (when the command goes remote), we use {{HashSet}}. However, this has drawbacks:
a) if the set passed to command uses different means of equality than {{Object.hashCode()}} and {{Object.equals()}] we may lose some keys in the derived set - we don't inject dataContainer's keyEquivalence to the commands
b) as these sets are usually just iterated through (contains() is rare) it's less effective to use complex data structures as {{HashSet}} - plain {{ArrayList}} is sufficient.
