-------------------------------------------

             Summary: ArrayIndexOutOfBoundsException in GridUnsafeLru
                 Key: IGNITE-3809
                 URL: https://issues.apache.org/jira/browse/IGNITE-3809
             Project: Ignite
          Issue Type: Bug
          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}
