I have got it once, and cannot reproduce for now.
Steps were approximately the following:
1. New project wizard.
2. Reach technologies page.
3. Hibernate = On, Generate config and main = On, Import database schema = On. JPA = On, Import database schema = On.
4. Finish. See the progress of jars importing. Cancel progress.
5. Change button. Set "Pick from disk" and pick nothing from disk. Close dialog. Finish.
6. Answer "Open in the same frame".
7. Get IDS dialog from Hibernate. Import some table with mapping to .orm.xml.
8. Get IDS dialog from JPA. Import some different table with mapping via annotations.
At this step I've got trace.
