Thanks for the feedback, see below.

In the second level cache we separate each entities 2LC cache into a separate cache instance? I think the latter would make it easier to support situations where certain entities are deployed in classloader isolation and some others are not, and might make it easier to define eviction/expiry settings on a per entity type. 

Can you detail what's the classloader isolation issue is about? FYI, I only store "primitive types" just like a database would do. I don't store any high level type.

And for the current goal, eviction policy would be tragic, we would lose data :)
But I agree, when we will target the Grid + JPA we might need some custom eviction policy per entity type though I wonder how we will be able to address query in this case.
I'll add a todo.
