@yrodiere Can’t understand why, but when I forced all my relations to LAZY, indexing is finished successfully. Before I had 29 LAZY relations and 3 EAGER relations (user roles to user and two similar).
As I switched to new Spring Boot and new Hibernate also, I have some issues with Thymeleaf and web mvc security which makes my app unusable, but here I’m showing an index from Luke which looks like somethint usable.
