Unclear failure description when adding elytron policy resource

When adding new Elytron policy resource, operation fails with [1]. In failure message there is missing "not" and for me, a user it is confusing since it says the policy provider which I am trying to add cannot be found...

[1]

[standalone@localhost:9990 /] /subsystem=elytron/policy=foo:add()
{
    "outcome" => "failed",
    "failure-description" => "Could find policy provider with name [foo]",
    "rolled-back" => true
}
