[jira] [Commented] (REEF-1473) Fix CanRunClrBridgeExampleOnLocalRuntime failures in AppVeyor

["Mariia Mykhailova (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/REEF-1473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15527616#comment-15527616 ] 

Mariia Mykhailova commented on REEF-1473:
-----------------------------------------

I haven't seen this error for the past two months. 

One thing we could do is to add check {{strStatus}} for null before {{Assert.True(strStatus.Equals("..."));}}, so that if the failure reappears, we have an explicit report of the cause.

> Looks like {{strStatus}} can be null sometimes due to some await problem.
