> Key: IGNITE-3809

> Project: Ignite

> Components: cache
> Affects Versions: 1.7
> Reporter: Valentin Kulichenko

> Fix For: 1.8
>
>
> {{GridUnsafeLru.offer(..)}} method uses atomic integer as a counter. In case
> of integer overflow this method will throw {{ArrayIndexOutOfBoundsException}}.
> We should use {{abs}} to avoid this. For example, like this:
> {code}
> return lrus[U.safeAbs(addIdx.getAndIncrement()) % cnt].offer(part, addr,
> hash);
> {code}
