Raymond Wilson created IGNITE-8590:
--------------------------------------
Summary: Overridden members in descendant classes can cause
BinaryMarshaller exceptions
Key: IGNITE-8590
URL: https://issues.apache.org/jira/browse/IGNITE-8590
Project: Ignite
Issue Type: Bug
Components: general
Affects Versions: 2.4
Environment: Apache Ignite 2.4 using .Net client with .Net Standard
artifacts.
Reporter: Raymond Wilson
If you define a pair of classes, one descended from the other, with an
overridden field, the Ignite binary marshaller throws the exception shown
below.
public class A
{
public int Filters;
}
public class B : A
{
public int Filters;
}
This code compiles (with a warning about an overridden field that does not use
the C# 'new' annotation) and runs, but produces this exception if class B is
supplied to an Ignite Compute function as an argument.
