> When reading an object that contains an object array directly inside another object array from python, and attempting to write it back directly, the following error is raised:
> {code:java}
>   File ".../ignite-python-thin-client/pyignite/utils.py", line 69, in is_hinted
>     return isinstance(value, tuple) and len(value) == 2 and issubclass(value[1], IgniteDataType)
> TypeError: issubclass() arg 1 must be a class
> {code}
>  
> Sample reproduction:
>  
> {code:java}
> from pyignite import Client
> from pyignite.datatypes import ObjectArrayObject
> ignite = Client()
> with ignite.connect('localhost', 10800):
>     cache = ignite.get_or_create_cache('example')
>     example_nested = ((ObjectArrayObject.OBJECT, [1]), ObjectArrayObject)
>     example = (ObjectArrayObject.OBJECT, [example_nested])
>     print(example) #                             (-1, [((-1, [1]), <class 'pyignite.datatypes.complex.ObjectArrayObject'>)])
>     cache.put('example', example)
>     print(cache.get('example')) #                (3, [(-1, [1])])
>     cache.put('example', cache.get('example')) # TypeError: issubclass() arg 1 must be a class
>     print(cache.get('example'))
> {code}
