回答1:
It's caused by Windows, you should read about LOCKING STRATEGY.
https://docs.jboss.org/hibernate/search/3.2/reference/en/html_single/#search-configuration-directory-lockfactories

This version of Hibernate Search is extremely old; this issue could occasionally happen but was resolved. You need to update.
