Bugreport: NullReferenceExpetion when using dotConnect for Oracle 9.14 with the ADO.Net appender from log4net

[marcwittke]

When using dotconnect for Oracle as ADO.Net appender from log4net, a NullReferenceException is thrown when the log event does not have an exception and the event also doesn't get logged to the database table

Code: Select all

log4net:ERROR [AdoNetAppender] ErrorCode: GenericFailure. Exception while writing to database
System.NullReferenceException: Object reference not set to an instance of an object.
   at Devart.Data.Oracle.c9.a(aq A_0, Int32 A_1)
   at Devart.Data.Oracle.c9.a(Int32 A_0, eu A_1)

   at Devart.Common.DbCommandBase.ExecuteDbDataReader(CommandBehavior behavior, Boolean nonQuery)

   at log4net.Appender.AdoNetAppender.SendBuffer(IDbTransaction dbTran, LoggingEvent[] events)
   at log4net.Appender.AdoNetAppender.SendBuffer(LoggingEvent[] events)

Full repo can be found here https://github.com/marcwittke/Devart-Log4Net . Also proof that ODP.Net does not have this issue. I started to notice this behavior after upgrading from 9.4

Is someone listening here?

Since you create .NET Framework project, you should use local assemblies (Devart.Data.dll, Devart.Data.Oracle.dll) shipped with the installation of dotConnect for Oracle (not a NuGet).
