[jira] [Commented] (NIFI-4092) ClassCastException Warning during
cluster sync
[ https://issues.apache.org/jira/browse/NIFI-4092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16301903#comment-16301903 ]
Joseph Witt commented on NIFI-4092:
-----------------------------------
Talked with Gilman. He says "we have seen this before. It’s always been environmental. Look for differ versions of jaxb on the class path. This could be from different versions of java on different nodes or a modified lib dir where someone added a jaxb jar."
