Message Title

When configured to use MultiLineSqlScriptExtractor, Hibernate ORM fails to process this import.sql:

-- This file allow to write SQL commands that will be emitted in test and dev.
-- The commands are commented as their support depends of the database
-- insert into myentity (id, field) values(nextval('hibernate_sequence'), 'field-1');
-- insert into myentity (id, field) values(nextval('hibernate_sequence'), 'field-2');
-- insert into myentity (id, field) values(nextval('hibernate_sequence'), 'field-3');

This results in the given output (there’s definitely an exception in there, but I’m not sure where the rest comes from):

line 5:85 extraneous input '<EOF>' expecting {CHAR, ' ', '\t', NEWLINE, QUOTED_TEXT}

org.hibernate.tool.schema.spi.SqlScriptException: Error during sql-script parsing.
