public class CustomPermissionsURLClassLoader
extends URLClassLoader

CustomPermissionsURLClassLoader extends URLClassLoader, adding the abilty to programatically add permissions easily. To be effective for permission management, it should be run in conjunction with a policy that restricts some of the classloaders, but not all. It's not ordinarily used by PicoContainer, but is here because PicoContainer is common to most classloader trees.
