NPE in CacheNotifierImpl by LIRS eviction listener

Update testSimpleEvictionMaxEntries method of org.infinispan.eviction.impl.BaseEvictionFunctionalTest like below: public void testSimpleEvictionMaxEntries() throws Exception { // inserting 20 keys - values in a 10 sized cache ( keys from key-1 to key-20) for ( int i = 0 ; i < CACHE_SIZE* 2 ; i++) { cache.put( "key-" + (i + 1 ), "value-" + (i + 1 ), 1 , TimeUnit.MINUTES); } Thread.sleep( 1000 ); // sleep long enough to allow the thread to wake-up assert CACHE_SIZE >= cache.size() : "cache size too big: " + cache.size();   // and then reinsert the first 10 keys (key-1 to key-10) for ( int i = 0 ; i < CACHE_SIZE; i++) { cache.put( "key-" + (i + 1 ), "value-" + (i + 1 ), 1 , TimeUnit.MINUTES); } } Run the test method: mvn
