Memory leak with LIRS eviction strategy --------------------------------------- Key: ISPN-7246 URL: https://issues.jboss.org/browse/ISPN-7246 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.2.5.Final Environment: * Infinispan 8.2.5.Final Library mode * LIRS eviction strategy Reporter: ted won Labels: core, eviction, leak, lirs, strategy Attachments: reproducer.zip There is a memory leak with the default eviction strategy. It's a 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 retain 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.
