    [ https://issues.apache.org/jira/browse/PROTON-561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13966801#comment-13966801

Justin Ross commented on PROTON-561:
------------------------------------

Interesting.  It does contain the expected error message:
