        logger - logger to use for logging failures and redelivery attempts
        redeliveryProcessor - an optional processor to run before redelivery attempt
        redeliveryPolicy - policy for redelivery
        transactionTemplate - the transaction template
        retryWhile - retry while
        executorService - the ScheduledExecutorService to be used for redelivery thread pool. Can be null.
        rollbackLoggingLevel - logging level to use for logging transaction rollback occurred
        onExceptionOccurredProcessor - a custom Processor to process the Exchange just after an exception was thrown.

        This implementation will invoke ensure this occurs synchronously, that means if the async routing engine did kick in, then this implementation will wait for the task to complete before it continues.

        Parameters:
        exchange - the exchange
