EvictionConfiguration is deprecated in 9.1 as it is replaced by MemoryConfiguration. However, there are several places in the code where the memory configuration is not referenced, and instead relies upon EvictionConfiguration.
e.g.

• AdvancedCache.evict(...) logs a WARN when EvictionConfiguration.strategy().isEnabled() returns false - which is the default value.
• The PersistenceManager preload logic determines the number of entries to load based on EvictionManager.maxEntries(), instead of MemoryConfiguration.size()
