[SOLVED] Apache Isis: Java Type mapping failed

I have one problem with the open source estatio (that is built based on apache isis)

I've export data base schema first in DDL file. After that I have imported the DDL file in PostgresSQL 9.5. The application can be started. And some of fixture can be executed. The problem I have in "Estatio Demo Fixture". The application seems to import few fixtures until the application try to import org.estatio.fixture.financial.BankAccountForAcmeNl. Following exception occurs:

The id of CommunicationChanel is described like following in DB: "id int4 NOT NULL DEFAULT nextval('"IncodeCommunications"."CommunicationChannel_id_seq"'::regclass)"

The Id of this table is automatically created for each insert statement. In this case that is not an insert statement but a find statement without reference Id. I mean it looks up in CommunicationChanelOwnerLink, if there is any row with id is blank.

public void setObject(PreparedStatement ps, int param, Object value)
{
    try
    {
        if (value == null)
        {
            if (column != null && column.isDefaultable() && column.getDefaultValue() != null && !StringUtils.isWhitespace(column.getDefaultValue().toString()))
            {
                ps.setLong(param, Long.valueOf(column.getDefaultValue().toString().trim()).longValue());
            }
            else

this block code of BigIntRDBMSMapping says that, if the value is null (that is exactly in this case) then it will try to parse default value that was initialized by datanucleus before. In this case, default value = "nextvalIncodeCommunications.CommunicationChannel_id_seq::regclass". This value can not be convert to Long value.

Any idea what is exactly happen here? Thanks.
