[~nizhikov] Looks good to me

> Service interface itself looks like this:
> {code:java}
> public interface SomeService : IService
> {
> int processSomething(int foo, Parameter[] parameters);
> int processSomething(int foo, int bar);
> }
> public class Parameter
{
> private int id;
> private ParamValue[] _values;
> public Parameter(int id, ParamValue[] _values)
{
> this.id = id;
> this._values = _values;
> }
>
}
>
public class ParamValue
{
> private int id;
> private double val;
> public ParamValue(int id, double val)
{
> this.id = id;
> this.val = val;
> }
>
}
> {code}
> And the call to the service:
> {code:java}
> var svc = igniteServices.GetServiceProxy<T>(name, false);
> var result = svc.processSomething(id, parameters);
> {code}
> Please note, that if there's no overloaded methods, at least in our
> experiments we found out that it does reproduce with equal number of
> parameters in overloaded methods (e.g. here we have overloaded methods that
> take 2 parameters each), then the code works like a charm.
> Fix in IGNITE-12823 addresses particular code execution path where the
> execution flow goes through PlatformServices class. Yet in this case our code
> goes through PlatformAbstractService. I think that the fix of casting arrays
> should be positioned a little bit lower in the call stack (or higher in code
> hierarchy) so all execution paths are covered simultaneously.
