Alexey Kuznetsov commented on IGNITE-3244:
------------------------------------------
[~vozerov] If you look at CacheObjectContext#unwrapBinary() you will see at the
end : co.value(this, cpy) . Which evaluates unmarshelling
> Custom arrays are not serialized properly by CacheObjectBinaryProcessorImpl

> Key: IGNITE-3244
> URL: https://issues.apache.org/jira/browse/IGNITE-3244
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: ignite-1.4
> Reporter: Denis Magda
> Assignee: Alexey Kuznetsov
> Priority: Minor
> Fix For: 2.0
>
>
> If to put a custom object array into a cache like this one
> {code}
> TestObject[] arr = new TestObject[] {new TestObject(i)};
> cache.put(0, arr);
> {code}
> then it will be serialized as Object[] array in
> {{CacheObjectBinaryProcessorImpl.marshallToBinary}} method.
> This leads to the situation when object's array type is lost and on cache.get
> the code below produces {{ClassCastException}}
> {code}
> TestObject[] obj = cache.get(i);
> {code}
> The full test is already added into
> {{GridCacheBinaryObjectsAbstractSelfTest.testCustomArrays}}.
> To fix the issue we have to revisit logic of
> {{CacheObjectBinaryProcessorImpl.marshallToBinary}} and
> {{CacheObjectContext.unwrapBinary}}.
