[rules-users] equality-based assert behavior and findFactHandle

[Edson Tirelli]

    Adam,

    Yes, you are right. I'm not sure why it uses the identity map instead of
assert map, but maybe we should change that or at least providing an
alternative method for that. May I ask you please to open a JIRA for it?

    Mark, are you ok with changing the behavior?
