When import files is empty string,
line 484, no check for importFiles to be empty, this leads to a ScriptSourceInput pointing on a folder of which content will be listed in the generated DDL (on this machine ~ /Library/Java/Extensions/driver/)
And if org.hibernate.cfg.AvailableSettings.HBM2DDL_IMPORT_FILES is not set to empty then import.sql is automatically added which is not intended in a DDL.
(setting it to null generates a NPE)
Current workaround it to set it to an empty file.
