HandlerTimeoutException
class HandlerTimeoutException(val subscription: String, val ref: AggregateRef, val version: Int, val timeout: Duration) : IllegalStateException
An attempt of subscription's handler at ref's version that ran longer than its budget's timeout (HandlerRetry.timeout, @Retry(timeout)): it was cancelled and counts as a failed attempt, retried like any other failure. The runtime's subscriptions and the test DSL throw it alike.
