hello @gunnar, sorry, so taking your example here - things are pretty easy once you specify this:

Method method = JobApi.class.getDeclaredMethod( "findJob", UUID.class );

You are actually explicitly telling what the T param is : UUID. What if you specify Object.class? Then it will break.

I've also opened the issue in spring and they sort of hacked it in the spring itself, but it seems that the problem is still in hibernate.

Here is the link: https://jira.spring.io/browse/SPR-12237
