[ https://issues.apache.org/jira/browse/BEAM-6839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17351298#comment-17351298 ]
Brian Hulette commented on BEAM-6839:
-------------------------------------
[~bala.divvela] I think the issue here is we haven't been able to reproduce the problem. Are you seeing it reliably?
If so it would be helpful to know what is on your classpath and/or what dependencies you're using in your project.
