> {{NullPointerException}} occurs in {{org.apache.ignite.internal.MarshallerContextImpl#registerClassName}} on trying to compare {{mappedName.className()}} of already existed {{typeId}} mapping with the new one {{clsName}} has come as a parameter.
> Actually {{org.apache.ignite.internal.processors.marshaller.MappedName#className}} may not be null but it was. So we should check {{clsName}} comes in {{MappedName}} constructor, to prevent same NPEs in the future.
