Sanne Grinovero commented on HSEARCH-517:
-----------------------------------------

maxxedit, thanks for noticing. Yes indeed it seems fishy, but afaik it worked, likely as usually there was just one entry in the iterator.
Anyway org.hibernate.search.event.ContextHolder was removed from the sources, you refer to an outdated issue. Please create a new issue affecting 3.2 only if you're able to reproduce this.
