------------------------------------
Hi [~slukyanov],Here is my investigation:
--
org.apache.ignite.internal.processors.cache.GridCacheProcessor#prepareCacheStart
----- *call
org.apache.ignite.internal.processors.cache.GridCacheProcessor#createCache* at
line #1944
----- *startCache(cache, desc.schema() != null ? desc.schema() : new
QuerySchema());* at line #1963
For case using *FifoEvictionPolicyFactory* and *LruEvictionPolicyFactory* the
backend eviction policy is generated by factory's *create()* method when
starting a cache. That's to say even through the eviction factory full fill the
*MBean interface or IgniteMBeanAware interface*, it can still not be registered
at
*org.apache.ignite.internal.processors.cache.GridCacheProcessor#registerMbean*,
as the instances have not been generated.
so I think the best place to register the mbeans is in
*org.apache.ignite.internal.processors.cache.GridCacheEvictionManager*.
please advise me if I am wrong.

> Key: IGNITE-8776

> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.5
> Reporter: Stanislav Lukyanov
> Assignee: kcheng.mvp
> Priority: Minor
> Labels: newbie
>
> Eviction policy MBeans, such as LruEvictionPolicyMBean, are never registered
> if evictionPolicyFactory is set instead of evictionPolicy (the latter is
> deprecated).
> This happens because GridCacheProcessor::registerMbean attempts to find
> either an *MBean interface or IgniteMBeanAware interface on the passed
> object. It works for LruEvictionPolicy but not for LruEvictionPolicyFactory
> (which doesn't implement these interfaces).
> The code needs to be adjusted to handle factories correctly.
> New tests are needed to make sure that all standard beans are registered
> (IgniteKernalMbeansTest does that for kernal mbeans - need the same for cache
> beans).
