ignite-2273 : Optimized usage of Arrays.asList().
----
> Arrays.asList() should not be used for 1- and 2- elements.
> ----------------------------------------------------------
>
> Key: IGNITE-2273
> URL: https://issues.apache.org/jira/browse/IGNITE-2273
> Project: Ignite
> Issue Type: Sub-task
> Components: general
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Ilya Lantukh
> Fix For: 1.6
>
>
> There are several places in code where Arrays.asList is used as follows:
> 1) For a single element. These places should be replaced with
> Collections.singleton() to avoid unnecessary array allocations.
> 2) For two elements. Here we should create our own "doubled-singleton"
> implementation.
> Some of these places are located on hot code paths (e.g. cache PUT).
