      <P> There are two primary reasons for creating a new loader
      instead of defining these bytecodes directly into the defining
      loader of the target class: first, it avoids any possible
      security risk of having these bytecodes in the same loader.

      than would otherwise be possible, decreasing run-time
      footprint. </P>
