Spring Boot 3 + Hibernate 6 + Ehcache 3 problem in creation of caches

Question

I got weired log when starting exception. I get message from hibernate that cache is created with default configuration and then next log is that ehcache created cache. Do I have 2 caches created or it is bad thing. I am providing below configuration and code:

ehcache.xml which is in my resource folder

<?xml version="1.0" encoding="UTF-8"?>
