> On OFFHEAP_TIERED TRANSACTIONAL cache:
> 1. Put entry.
> 2. Cache size equals 1 and iterator returns one entry.
> 3. Open PESSIMISTIC READ_COMMITED transaction.
> 4. get() that value.
> 5. Commit transaction.
> 6. Cache size now equals 2 and iterator returns two identical entries.
> By fast investigation was found that after put() operation value goes to 
> offheap. After get() operation in explicit transaction the same value appears 
> in onheap and offheap iterators. As a result user sees two the same entries.
