How could `ivSpec` be non-null here? IIUC the only answer is from a previous
`engineInit`, and it should not be retained. I suggest removing this check plus
adding an explicit `ivSpec = null` at the beginning of this method along with
`iCount` and `salt`. Those are the only 3 non final instance fields.
