regarding:
https://docs.jboss.org/hibernate/orm/5.2/javadocs/org/hibernate/hql/internal/ast/ASTQueryTranslatorFactory.html

the API-Docs of Hibernate 5.2 of ASTQueryTranslatorFactory.createQueryTranslator do not document the last parameter:
EntityGraphQueryHint ...

We have the following sample (convert JP-QL to SQL):
String hqlQueryString = query.unwrap(org.hibernate.Query.class).getQueryString();
ASTQueryTranslatorFactory queryTranslatorFactory = new ASTQueryTranslatorFactory();
SessionImplementor hibernateSession = em.unwrap(SessionImplementor.class);
QueryTranslator queryTranslator = queryTranslatorFactory.createQueryTranslator("", hqlQueryString, java.util.Collections.EMPTY_MAP, hibernateSession.getFactory(), EntityGraphQueryHint.class.);
queryTranslator.compile(java.util.Collections.EMPTY_MAP, false);
String sqlQueryString = queryTranslator.getSQLString();

Please document this property so that it is clear how to set the last parameter
