* the Bundle ? You can certainly take a class inside the bundle and get the
* bundle's classloader that way. Getting the classloader directly from the
* bundle would be nice.
* <p>
* We could use fragments that are specific to each OSGi implementation. Using
* introspection here to keep packaging simple and avoid the multiplication of
* the jars.
* </p>
* <p>
* The default implementation relies on introspection and supports equinox-3.5
* and felix-2.0.0
