Doc Text:	The <literal>evictions</literal> attribute of <classname>Statistics</classname> and <classname>ClusterCacheStats</classname> components of the Cache MBean return zero even though some eviction operations have been successfully performed. This issue only affects statistics, not the actual eviction process. This is a known issue in Red Hat JBoss Data Grid 6.6.0, and no workaround exists at this time.	Story Points:	---

Description Osamu Nagano 2016-01-20 01:25:46 UTC

Description of problem:
Eviction is working because numberOfEntries never exceeds maxEntries.  But "evictions" attribute displays always 0 in JMX.

Version-Release number of selected component (if applicable):
JDG 6.5.1 (Infinispan 6.3.1.Final-redhat-1)

How reproducible:
Always.

Steps to Reproduce:
1. Set eviction like <eviction strategy="LRU" max-entries="10"/> in a JDG server.
2. Put entries more than the max-entries.
3. Check Statistics.evictions and ClusterCacheStats.evictions of the cache in JConsole.

Actual results:
evictions is always 0.

Expected results:
evictions should be the count of evicted entries.

Additional info:
This issue found in both of server and library modes.
