Pavel Tupitsyn commented on IGNITE-5927:
----------------------------------------
I've reproduced the issue, and I would say that this is a bug in
{{System.Data.DataTable}}. Here is the code:
{code}
public virtual void GetObjectData(SerializationInfo info, StreamingContext
context) {
SerializationFormat remotingFormat = RemotingFormat;
bool isSingleTable = context.Context != null ?
Convert.ToBoolean(context.Context, CultureInfo.InvariantCulture) : true;
SerializeDataTable(info, context, isSingleTable, remotingFormat);
}
{code}
Exception comes from {{Convert.ToBoolean(context.Context,
CultureInfo.InvariantCulture)}}
The assumption that {{Context}} can be converted to bool does not look correct,
see MSDN https://msdn.microsoft.com/en-us/library/h58hxyt6(v=vs.110).aspx:
{code}additional: Any additional information to be associated with the
StreamingContext.{code}
Anyway, .NET framework is not going to be fixed, so we have to get rid of
{{BinaryWriter}} in that context.
