---------------------------------------
[~agoncharuk] [~sboikov], should we delete test code
org.apache.ignite.internal.processors.cache.GridCacheSwapPreloadSelfTest#checkSwapMultithreaded()
?
> Race in preloading/unswapping

> Project: Ignite
> Issue Type: Bug
> Components: cache
> Reporter: Semen Boikov

> Fix For: 2.0

>
> During unswap entry is removed from swap then unswap listener is notified,
> and this logic in preload supply worker:
> - register unswap listener
> - iterater over heap
> - iterate over swap
> - remove unswap listener
> - iterate over entries recorded by unswap listener
> There is a race: entry is removed from unswap, listener is not notified yet,
> at this moment supply worker removes unswap listener.
> These tests fail from time to time because entry can be missed during
> preloading:
> GridCacheSwapPreloadSelfTest.testSwapPartitionedMultithreaded
> GridCacheSwapPreloadSelfTest.testSwapReplicatedMultithreaded
