I would like a cache library in Java with the following features:

• Create multiple caches
• The size of all the caches together should be limited by a memory (e.g. 10GB)
• The caches should remain in heap

I know of Ignite cache, which supports the first 2 bullets, but is an off-heap cache, involving serialization and deserialization.
EhCache support a memory limit, but for each individual cache.
