I think Stefan is correct here - but then, for a Java based tool (that
is non-ANT compliant, ala JDMK) what is the proper way to launch?
"exec" to kick off another VM that way?

Let me first say that I don't know anything about MIB.

Are you sure the class MibGen follows the patterns of an Ant task?

We'd have the following requirements:

(1) public no-arg constructor

(2) A method of the signature public void setLine(SomeType) where
SomeType is String, a primitive type, wrapper class for a primitive
type, Class, File or any Type with a public one-arg-String
constructor.

(3) A method of the signature public void execute()

This here

> java.lang.InstantiationException: com.sun.jdmk.tools.MibGen

looks as if condition (1) wouldn't be true.
