We had a problem with this file last night. Fixed it by switching from http://hibernate.org/dtd/hibernate-mapping-3.0.dtd to http://[hibernate.sourceforge.net/hibernate-mapping-3.0.dtd|http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd]

See https://hibernate.atlassian.net/browse/HHH-13469 and https://stackoverflow.com/questions/56792434/im-getting-xmlstreamexception-at-row-col1-2
