Printing out a table.first or table.where(Selection) causes an exception

[pyrator]

The table has been read from a csv file. Altering the table and viewing the table structure or saving to csv file works ok, but
System.out.println(table.first(10)); causes:
Receiver class tech.tablesaw.selection.BitmapBackedSelection$1 does not define or inherit an implementation of the resolved method 'abstract java.lang.Object next()' of interface java.util.Iterator.
Selection smallToken = tokenColumn.isLessThan(1001);
Table resultTable = table.where(smallToken); also causes:
Receiver class tech.tablesaw.selection.BitmapBackedSelection$1 does not define or inherit an implementation of the resolved method 'abstract java.lang.Object next()' of interface java.util.Iterator.
During debugging the table itself is shown as an empty string, but the table structure, columnList etc. can be seen correctly.
I am running this with Java jdk-17.0.1 in Windows 11
the csv file has been downloaded from

Thanks
