[jira] [Commented] (IGNITE-5038) BinaryMarshaller might need to use context class loader for deserialization

Vyacheslav Daradur commented on IGNITE-5038:
--------------------------------------------

Hi, [~vozerov], [~v.pyatkov],

I have a use case where classes descriptions are owned by different classloaders.
I have to serialize objects myself and use {{IgniteCache}} via {{withKeepBinary}} mode in this case.

Completion of this task will allow us to use Ignite's serialization via efficient {{BinaryMarshaller}} and significantly improve performance.

As far as I can see you have prepared the solution, are you going to merge it?

> There is a special use case discussed on the dev list:
> http://apache-ignite-developers.2346864.n4.nabble.com/Re-BinaryObjectImpl-deserializeValue-with-specific-ClassLoader-td17126.html#a17224
> According to the use case, BinaryMarshaller might need to try to deserialize an object using a context class loader if it failed to do so with a custom classloader (`IgniteConfiguration.getClassLoader()`) or the system one.
