Subject [jira] [Commented] (IGNITE-8776) Eviction policy MBeans are never registered if evictionPolicyFactory is used

Stanislav Lukyanov commented on IGNITE-8776:
--------------------------------------------

[~kcheng.mvp] thanks for looking into this!

Yes, it seems that moving all responsibility for the eviction policy to the `GridCacheEvictionManager`
would be the best.
Roughly speaking, having a `prepare()` method in GridCacheEvictionManager same as the one
in the `GridCacheProcessor` seems alright.

> 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).
