As shown below, after run the method "au.org.ala.util.DwCALoader", our system returns the error message "Exception in thread "main" org.gbif.dwc.text.UnkownDelimitersException: Unable to detect field delimiter"

I accomplished tests using DwC-A files with tab-delimited text files and comma-delimited text files. In both cases the error generated was the same.
