Semen Boikov updated IGNITE-614:
--------------------------------
Description:
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
