+     * Tries to determine whether the given class is part of the framework or not.
+     * Framework classes include everything in org.apache.felix.framework.* and
+     * org.osgi.framework.*. We also consider ClassLoader and Class to be internal
+     * classes, because they are inserted into the stack trace as a result of
+     * method overloading. Typically, ClassLoader or Class will be mixed in
+     * between framework classes or will be at the point where the class loading
+     * request enters the framework class loading mechanism, which will then be
+     * followed by either bundle or external code, which will then exit our
+     * attempt to determine if we should boot delegate or not. Other standard
+     * class loaders, like URLClassLoader, are considered external classes and
+     * should trigger boot delegation. This means that bundles can create standard
+     * class loaders to get access to boot packages, but this is the standard
+     * behavior of class loaders.
+     * @param clazz the class to determine if it is external or not.
+     * @return <tt>true</tt> if the class is external, otherwise <tt>false</tt>.
