1 MessageSender Interface

The signature of the method sendDebitor in bakery.logic.communication.out.MessageSender interface has changed.
An InvoicingTransmissionDO is used as parameter instead of a DebitorTransmissionDO, see code snippet of the MessageSender-implementation.
All attributes which were used in DebitorTransmissionDO can be fetched from the InvoicingTransmissionDO and the attached InvoicingDO.

Furthermore, a default implementation exists for this method, so this method does not have to be implemented if there is no need.

@Override
public ProcessContainer sendDebitor(TransmissionWrapper transmissionWrapper,
                InvoicingTransmissionDO invoicingTransmissionDO) throws ValidationException
{
    // custom implementation
}

2 Custom Process Tasks

Remove custom process task implementations for CheckSendDebitorPT, this task doesn't exists anymore. The related field in ExpandedProcessTaskDefDO can be removed as well.
The decision if a transmission of a debtor is required or not is done by the CommunicationPartner configuration of type SEND_DEBITOR and the default decision bean SendDebtorDeciderBean with id 200.
