>                 Key: IGNITE-3240
>                 URL: https://issues.apache.org/jira/browse/IGNITE-3240
>             Project: Ignite
>          Issue Type: Bug
>          Components: binary, cache
>    Affects Versions: 1.1.4
>            Reporter: Pavel Tupitsyn
>            Assignee: Denis Magda
>            Priority: Blocker
>             Fix For: 1.7
>
>
> Code to reproduce:
> {code}
> IgniteCache<Integer, String[]> cache = ignite.getOrCreateCache(CACHE_NAME);
> cache.put(1, new String[]{"hello", "world"});
> String[] res = cache.get(1);
> {code}
> The bug is in CacheObjectContext.unwrapBinariesInArrayIfNeeded method, which always produces a new array.
> We should check for basic types somehow and skip this conversion.
> Generally, we NEVER want to change the type of the array, so the fix may be:
> {code}
> if (arr.getClass().getComponentType() != Object.class)
>     return arr;
> {code}
