[jira] [Commented] (GEODE-5228) ServerLauncherRemoteFileIntegrationTest fails intermittently with IllegalStateException vf.gf.server.status is blank

["Dan Smith (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GEODE-5228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16648382#comment-16648382 ] 

Dan Smith commented on GEODE-5228:
----------------------------------

I changed the pollDelay for the await() calls in this test to zero as part of GEODE-5424, which seems to make this failure more likely.

It looks like this is a race in the status() method - it can read an empty file before it is written. If that happens, it fails with this error instead of retrying in the await().
