 <P>
 Use a custom introspector that prevents classloader related method
  calls.  Use this introspector for situations in which template
  writers are numerous or untrusted.  Specifically, this introspector
  prevents creation of arbitrary objects or reflection on objects.

  <p>To use this introspector, set the following property:
  <pre>
  runtime.introspector.uberspect = org.apache.velocity.util.introspection.SecureUberspector
