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

             Summary: Custom arrays are not serialized/deserialized 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: Denis Magda
            Priority: Critical
             Fix For: 1.7


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}}.
