[teiid-issues] [JBoss JIRA] (TEIID-2244) dynamic VDB, UDF class not found

[Van Halbert (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2244?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12764503#comment-12764503 ] 

Van Halbert commented on TEIID-2244:
------------------------------------

Apologize for waisting your time.  It was the other dependencies that had me thinking it was the issue.  When I separated those out into their own module, the UDF no longer required a dependency to be added to teiid/main.
