[jira] [Updated] (IGNITE-3134) Unexpected EVT_CACHE_ENTRY_EVICTED events in OFFHEAP_TIERED mode

     [ https://issues.apache.org/jira/browse/IGNITE-3134?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexei Scherbakov updated IGNITE-3134:
--------------------------------------
    Description: 
EVT_CACHE_ENTRY_EVICTED event is triggered on any cache operation in this mode.

Code sample:

{code}
IgnitePredicate<CacheEvent> lsnr = new IgnitePredicate<CacheEvent>() {
        @Override public boolean apply(CacheEvent evt) {
                    System.out.println("Old value: " + evt.oldValue());
                    counter.incrementAndGet();
                    return true; // Return true to continue listening.
        }
};

CacheConfiguration<Object, Object> cfg = new CacheConfiguration<>();
cfg.setMemoryMode(CacheMemoryMode.OFFHEAP_TIERED);
cfg.setEvictionPolicy(new FifoEvictionPolicy<>(1));
IgniteCache<Object, Object> test = ignite.getOrCreateCache(cfg);

// Register event listener for all local task execution events.
ignite.events().localListen(lsnr, EVT_CACHE_ENTRY_EVICTED);

test.put("1", "1");
test.put("2", "2");
test.put("3", "3");
Object o = test.get("2");

System.out.println(counter.get());
{code}

will print 4
