--------------------------
    Description: 
There is a memory leak in org.infinispan.commons.util.concurrent.jdk8backported.BoundedEquivalentConcurrentHashMapV8 with LIRS eviction strategy.
There are cache entries in org.infinispan.container.DefaultDataContainer.entries and its size are bigger than cache size after eviction occurred.
DefaultDataContainer.entries retains keys and values for evicted entries in the cache.
After full GC, DefaultDataContainer.entries size wasn't changed.
The following minimum reproducer exhibits a leak. Eviction is supposed to suppress OOME.
