Looking at the code prior to
https://github.com/apache/storm/commit/861a92eab8740cfc0f83ac4d7ade9a2ab04a8b9b
null routing was silently ignored. I'm not sure that was on purpose though. I
am OK merging this in, but I really would like to understand why the
destination task is showing up as null occasionally, but I see that you
addressed that in the comments here
https://issues.apache.org/jira/browse/STORM-770?focusedCommentId=14499225&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14499225
So I am +1 for the change. At least now we explicitly handle the situation.
