      See SharingTest.testShouldAlphaShareBecauseSameConstantDespiteDifferentSyntax().

      value == 1

      and

      value == TestStaticUtils.return1()

      are shared when standard-drl. They have the same hashCode because it's calculated by fieldValue.

      This is wrong because we cannot guarantee that TestStaticUtils.return1() always returns 1. So we should not share the node in the case.

      Also the static method constraint should not be indexable (for both hash and range)

      age < StaticUtil.getThirty()
