Migrating from Hibernate ORM 4.2.21.Final to 5.3.5.Final. According to the Hibenate site we had to upgrade Hibernate Search as well. Upgraded from 4.4.4 to 5.10. Using ehcache 2.10.3 as second level caching provider.
Currently I’ve zero compile errors - though had to disable a bit of code to pull that of. When starting the server I got an error wrt the second level cache. I hoped to get further by disabling the cache all together by setting the following in the hibernate.properties file.
After doing that I still get the SAME error:
2018-08-16 14:56:44,493 [main] WARN in [org.hibernate.cache.ehcache.internal.EhcacheRegionFactory.<init>(EhcacheRegionFactory.java:58)] - HHH020100: The Ehcache second-level cache provider for Hibernate is deprecated. See https://hibernate.atlassian.net/browse/HHH-12441 for details. 2018-08-16 14:56:49,874 [main] WARN in [org.hibernate.cache.ehcache.internal.EhcacheRegionFactory.createCache(EhcacheRegionFactory.java:153)] - HHH90001006: Missing cache[default-update-timestamps-region] was created on-the-fly. The created cache will use a provider-specific default configuration: make sure you defined one. You can disable this warning by setting 'hibernate.cache.ehcache.missing_cache_strategy' to 'create'. 14:56:49.895 [main] ERROR o.s.web.context.ContextLoader - Context initialization failed org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.cache.spi.CacheImplementor]
Another snippet where it goes wrong:
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:708) at eu.mycompany.orm.impl.SessionFactoryBuilderImpl.buildSessionFactory(SessionFactoryBuilderImpl.java:112) <--------- error starts here.
Perhaps I’m misinterpreting things but I thought the settings would prevent ehcache from being started by the Hibernate buildSessionFactory. Its ofc entirely possible its caused by something else during the migration but I like to rule things out. Any hint/pointers, its very much appreciated.
Note: I guess I can forget about the WARN text. Upgrading to ehcache 3.5.2 is planned after the migration.
