Andrey Gura commented on IGNITE-1380:
-------------------------------------

There ar two problems in case of near cache:

# {{GridNearCacheAdapter.randomEntry()}} method returns {{GridDhtAtomicCacheEntry}} instance instead of {{GridNearCacheEntry}}.
# {{RandomEvictionPolicy}} always use {{IgniteCache.localSize(CachePeekMode.ONHEAP)}} call for size calculation.

PR cretaed: https://github.com/apache/ignite/pull/185

Waiting for TC.
