Vladimir Ershov commented on IGNITE-10:
---------------------------------------

Ok, I suppose it's due to calling from Gateway. I'will create a separate ticket for it, since
it's a separate task.

> Current solution: serialize grid name, then find comp by name on peer.
> Current solution not working: in our internal unit tests, in distributed topology when
user gives different names to nodes 
> New solution: each grid thread should know its node. So, on deserialization we cast thread
to e.g. IgniteThread and take its holding component from it. If it is not IgniteThread then
exception should be thrown since it is anyway impossible to deserialize component outside
of context.
> Suggestion from IGNITE-553:
> As we moving to java8 lambdas, it is impossible to use @IgniteInstanceResource in lambdas.
As a result, single-jvm ping-pong test does not work.
> Suggested fix:
> Introduce a static thread-local field which will be set before processing a message and
will be nullified after message is processed. IgniteKernal should check this thread-local
in readResolve and return this instance.
