Got an Unexpected exception when starting the server, after digging, I think the message should have indicated that the UDF requires static methods
---------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: TEIID-1279
                 URL: https://jira.jboss.org/browse/TEIID-1279
             Project: Teiid
          Issue Type: Bug
          Components: Server
            Reporter: Van Halbert
            Assignee: Steven Hawkins
            Priority: Minor
             Fix For: 7.1.1


When trying to start the server got this exception:

Caused by: Unexpected exception while loading org.teiid.translator.jdbc.modeshape.functions.Cast.public java.lang.Object org.teiid.translator.jdbc.modeshape.functions.Cast.cast(java.lang.String,java.lang.String) with args= [class java.lang.String, class java.lang.String]

After digging into the code, I realized that the function methods are required to be static.   It sure would have been nice if the error would have indicated the reason.  And I can see this error happening in development.
