-------------------------------------
Release Note: Fixed nested object array deserialization
> Python nested object arrays re-serialization failure
> ----------------------------------------------------
>
> Key: IGNITE-15266
> URL: https://issues.apache.org/jira/browse/IGNITE-15266
> Project: Ignite
> Issue Type: Bug
> Components: python, thin client
> Affects Versions: python-0.5.1
> Reporter: Bojidar Marinov

> 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}
>
