> Throwing an exception as a result of a normal situation is extremely bad in

> Key: LUCENENET-8
> URL: https://issues.apache.org/jira/browse/LUCENENET-8
> Project: Lucene.Net
> Issue Type: Task
> Environment: Windows XP, Visual Studio 2003
> Reporter: Jo Inge Arnes

> At the end of the FastCharStream.Refill() method, it says:
> int charsRead = input.Read(buffer, newPosition, buffer.Length - newPosition);
> if (charsRead <= 0)
> throw new System.IO.IOException("read past eof");
> else
> bufferLength += charsRead;
> When I run Lucene in the debugger, this causes an exception to be thrown all
> the time.
> To me it looks like it is thrown as a result of a normal situation, not
> because of some critical error.
> Is this correct?
> If this is the case, then the code is horrible. Throwing an exception in .NET
> is extremely slow, and should never be thrown as a result of a normal
> situation. I repeat: "extremely slow"
