> When there is a loadClass(String) to a classloader it simply calls loadClass(String,
boolean). The second function checks if a class is available in the parent classloader by
checking loadClass(String, boolean). If BundleToClassLoader adapter is used for a ClassLoader
as the parent, the loadClass(String) will never be called.
