UnreadableEventException
class UnreadableEventException(val ref: AggregateRef, val version: Int, val name: String, val revision: Int, val cause: RuntimeException) : IllegalStateException
An event of ref's stream at version that its model cannot read: its record name at revision fails to decode or to upgrade, as cause says. The kernel throws it from rebuilding a state, so the failure names the aggregate. It classifies as its cause does: a handler's @Retry lists and the failure classifiers see through it (FailureClassification).
