Hi devs.
I am running ignite github master branch. My case is simple, use OFF_HEAP and enable swap. For I know this bug (https://issues.apache.org/jira/browse/IGNITE-3840) isn't merge into the master. So I disable any expiry policy. After running for a while, I checked the memory usage of ignite. I can see Java heap memory keep growing. I dump the heap and using MAT to analyze and found: Most memory ase used by org.apache.ignite.spi.swapspace.SwapKey. It is a bug or designed purposely? I need a stable version of no memory issue, I tried 1.7.0, 1.8.0 master and some pull request version, but none of them work. Please help. Thanks
