NPE in Infinispan EvictionManagerImpl when statistics are enabled on a simple cache ----------------------------------------------------------------------------------- Key: ISPN-10006 URL: https://issues.redhat.com/browse/ISPN-10006 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.4.8.Final, 10.0.0.Beta2 Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Major Fix For: 10.0.0.Beta4 I enabled statistics through attribute "statistics-enabled" within the infinispan subsystem on all cache-containner's and all local-cache's using standalone-full.xml as the base. After some time I see NullPointerExceptions with this stacktrace: {noformat} 22.02. 10:46:31,422 WARNING [com.github.benmanes.caffeine.cache.BoundedLocalCache#lambda$notifyRemoval$1] Exception thrown
