Steven Hawkins commented on TEIID-2244:
---------------------------------------

> and without specifying the dependency in teiid/main module, the ClassNotFoundException is seen.

Users should never modify our module dependencies.

You need to validate that org.jboss.teiid.businessrules.udf is the name of the module and that it completely defines all of the necessary dependencies.
