William Burns commented on ISPN-8325:
-------------------------------------

We can't really support a cache size of 0 with eviction. Thus I would say we should probably make sure that documentation states this as well. [~pferraro] you were referring to https://github.com/infinispan/infinispan/blob/master/core/src/main/java/org/infinispan/configuration/cache/MemoryConfiguration.java#L50 as the line talking about -1 or was it some where else?

> The documentation for MemoryConfiguration explicitly states that eviction is disabled if size < 0, however, this method returns false if size = 0.
> Configuring MemoryConfigurationBuilder with size(0L) causes evict(...) to log a confusing WARN message:
> WARN: ISPN000419: Eviction of an entry invoked without an explicit eviction strategy for cache foo
