This was originally reported to as a [bug|https://github.com/EsotericSoftware/kryo/issues/934] to my project, but I think that this is something that has to be resolved in Hibernate itself.
{{CacheKeyImplementation}} implements Serializable, but cache keys for some types have fields that are not serializable. See the following stacktrace:
{noformat}Caused by: org.hibernate.cache.CacheException: com.esotericsoftware.kryo.KryoException: java.lang.reflect.InaccessibleObjectException: Unable to make field private transient volatile boolean java.lang.reflect.Executable.hasRealParameterData accessible: module java.base does not "opens java.lang.reflect" to unnamed module @2c13da15

Cache keys for {{org.hibernate.type.EmbeddedComponentType}} contain a reference to {{java.lang.reflect.Field}} via {{org.hibernate.tuple.component.PojoComponentTuplizer}}.
Classes in {{java.lang.reflect}} are not serializable.
This issue has been resolved in Hibernate 6 where cache keys no longer reference the type itself, but the disassembled state of the type.
Does it make sense to backport the changes from to cache keys from Hibernate 6 to 5? |
