NPE in CacheNotifierImpl by LIRS eviction listener --------------------------------------------------- Key: ISPN-7080 URL: https://issues.jboss.org/browse/ISPN-7080 Project: Infinispan Issue Type: Bug Components: Test Suite - Core Affects Versions: 9.0.0.Alpha4 Environment: * Infinispan branch: Upstream master Reporter: Ted Won Assignee: William Burns Labels: core, eviction, lirs Fix For: 9.0.0.Beta1 The LIRSEvictionFunctionalTest.testSimpleEvictionMaxEntries unit test method in core module fails and throws NPE in CacheNotifierImpl.notifyCacheEntriesEvicted method when trying to reinsert the first keys again. https://github.com/infinispan/infinispan/blob/master/core/src/test/java/o... It reproduces only with LIRS eviction strategy and eviction listener. However, LRU and UNORDERED eviction strategies are working properly. It makes impossible the use of eviction listeners with LIRS eviction strategy. It's able to reproduce by: - inserting 20 keys - values in a 10 sized cache ( keys from key-1 to key-20), - and then reinsert the first 10 keys (key-1 to key-10)
