JBC3.0 solves this problem much nicely: you are allowd to specify an EvictionActionPolicy for each evcition algorithm. EvictionActionPolicy refers to allowing one to do to-disk eviction, remove from memory or whatever strategy is chosen.

I guess what you need here is passivation:
<passivation>false</passivation>
Take a look at what passivation can do for you in the user guide.

That is because when you do cache.remove within your custom eviction, this will go through the interceptor chain and remove data from DB, as per a normal cache.remove. Again, passivation should solve this issue for you.
