--------------------------------------------
[~avinogradov]
The most deep point of the error: {{IgniteUtils#forName}}
{{java.lang.ClassNotFoundException: sun.reflect.GeneratedMethodAccessor##}}
It is called by {{OptimizedMarshallerUtils#classDescriptor}} via
{{MarshallerContextImpl#getClass}}
{code}
cls = ctx.getClass(typeId, ldr); // couldn't load class for current typeId
// cls is null, but mustn't be null
OptimizedClassDescriptor desc = clsMap.get(cls); // NullPointerException
{code}
As far I know GeneratedMethodAccessor are classes wich generated at runtime by
the Java-reflection to call methods and constructors.
As I understand, one node serialized self-generated reflection class, and other
node tryed to deserialize it.
