             Summary: NPE in CacheNotifierImpl by LIRS eviction listener 
                 Key: ISPN-7082
                 URL: https://issues.jboss.org/browse/ISPN-7082
             Project: Infinispan
          Issue Type: Bug
          Components: Test Suite - Core
    Affects Versions: 9.0.0.Alpha4
         Environment: * Infinispan branch: Upstream master
            Reporter: Wolf-Dieter Fink
            Assignee: ted won


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/org/infinispan/eviction/impl/LIRSEvictionFunctionalTest.java
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)
