[jira] [Commented] (LUCENENET-496) System.NotImplementedException
occurred in Microsoft.VisualStudio.QualityTools.Common.dll
[ https://issues.apache.org/jira/browse/LUCENENET-496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13398510#comment-13398510 ]
Simon Svensson commented on LUCENENET-496:
------------------------------------------
QueryParserTokenManager.InitBlack creates a StreamWriter for debugging purposes. It will write to Console.OpenStandardOutput() using Console.Out.Encoding, and the later is a NotSupportedOperation for EqtStringPerThreadWriter (which is a TextWriter). I would guess that the testing framework sets Console.Out to a new EqtStringPerThreadWriter, and you may be able to workaround this issue by Console.SetOut(new StreamWriter(new MemoryStream())) before creating the QueryParser.
I'm not sure who uses the writer created by QueryParserTokenManager, and why Console.Out isn't used directly.

> Key: LUCENENET-496
> URL: https://issues.apache.org/jira/browse/LUCENENET-496
> Project: Lucene.Net
> Issue Type: Bug
> Components: Lucene.Net Core
> Affects Versions: Lucene.Net 2.9.4g
> Environment: VS2010sp1 + mstest on win7 64-bit
> Reporter: Nicklas Norling
> Priority: Minor
>
> When enabling parallel tests in VS2010 one of our tests failed consistently with a weird NotImplementedEsxception inside the MS tool.
> The following code is use Lucene.NET 2.9.4.1 from NuGet:
> analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_29);
> parser = new QueryParser(Lucene.Net.Util.Version.LUCENE_29, "All", analyzer);
> The exception is thrown inside the new QueryParser call. This is the call stack:
> System.NotImplementedException was unhandled by user code
> Message=The method or operation is not implemented.
> Source=Microsoft.VisualStudio.QualityTools.Common
