Description

This issue relates to IGNITE-12823.

Ignite client calls deployed service and fails with the following exception:

Service interface itself looks like this:

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;
  
    }

}

And the call to the service:

var svc = igniteServices.GetServiceProxy<T>(name, false);
var result = svc.processSomething(id, parameters);

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.
