[hibernate-dev] Caching @EmbeddedId/@Embeddable instances

[Galder Zamarreño]

Hi all,

Re: https://community.jboss.org/message/739399#739399

This guy's using a combo of @EmbeddedId and @Embeddable in the tests his provided, and this is resulting in cache key serialized payloads differing for identical instances. Even in between runs, the last bit of the payload varies. This obviously results in keys not being found in the cache. 

Apart from this issue which I'm currently investigating, I've spotted that when the CacheKey is marshalled, it also marshalls the entity as part of the key. That sounds rather inefficient, so is this guy:

a) using the right pattenr for @EmbeddedId + @Embeddable
b) is Hibernate behaving the right way here by having a reference to the entity from cache key

Cheers,
