>             Project: Infinispan
>          Issue Type: Bug

>    Affects Versions: 9.0.0.Alpha4
>         Environment: * Infinispan branch: Upstream master

> 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)
