> 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).
