> h2. Notes
> Having key classes with fields not participating in *equals* operation leads to errors when handling them in B+Tree data structures.
> It is discussed here in more details: [dev-list discussion|http://apache-ignite-developers.2346864.n4.nabble.com/Stable-binary-key-representation-td15904.html]
> h2. Acceptance Criteria
> # All classes known to have such flaw are replaced at run time to use them safely within B+Tree.
> # All tests marked with this issue number are passing.
> h2. Out-of-scope
> *BinaryIdentityResolver* approach is deprecated when solution described above is implemented and proven to be working.
