Summary: .NET NullReferenceException when serializing fields of the same type in different order
Key: IGNITE-12860
URL: https://issues.apache.org/jira/browse/IGNITE-12860
Project: Ignite
Issue Type: Bug
Affects Versions: 2.8
Reporter: Alexey Kukushkin

.NET NullReferenceException when serializing fields of the same type in different order
+*Steps to reproduce*+:
* Implement IBinarizable for a type having multiple fields and randomly select subset of the fields in the IBinarizable.WriteBinary implementation
* Serialize the type multiple times
+*Actual result*+:
Eventual NullReferenceException at some iteration of serialization:
{{Object reference not set to an instance of an object. }}{{at Apache.Ignite.Core.Impl.Binary.Structure.BinaryStructure.GetFieldId(String fieldName, Byte fieldType, Int32& pathIdx, Int32 actionIdx)}}{{ at Apache.Ignite.Core.Impl.Binary.Structure.BinaryStructureTracker.GetFieldId(String fieldName, Byte fieldTypeId)}}{{ at Apache.Ignite.Core.Impl.Binary.BinaryWriter.WriteFieldId(String fieldName, Byte fieldTypeId)}}{{ at Apache.Ignite.Core.Impl.Binary.BinaryWriter.WriteInt(String fieldName, Int32 val)}}{{ at Sbt.Cashflow.Grid.Ignite.Serialization.<>c.<.cctor>b__8_26(IBinaryWriter w, String k, Object v) in d:\Repos\Sbt.CMS.Cashflow\sbt.cashflow.grid.subrepo\Sbt.Cashflow.Grid\Sbt.Cashflow.Grid\Ignite\Serialization.cs:line 231}}{{ at Sbt.Cashflow.Grid.Ignite.Serialization.Write(IBinaryWriter writer, Type type, String name, Object val) in d:\Repos\Sbt.CMS.Cashflow\sbt.cashflow.grid.subrepo\Sbt.Cashflow.Grid\Sbt.Cashflow.Grid\Ignite\Serialization.cs:line 51}}{{ at Sbt.CMS.Infrastructure.Ignite.Objects.CacheItem.WriteBinary(IBinaryWriter writer) in d:\Repos\Sbt.CMS.Cashflow\sbt.cms.subrepo\Sbt.CMS.Infrastructure\Ignite\Objects\CacheItem.cs:line 162}}
