  27  * security manager, the same package access restrictions should be in effect
  28  * as when the default java.lang.SecurityManager is set, which with the
  29  * default "java.security" file in the JDK means that access to packages in
  30  * the sun.* package hierarchy is denied (without explicit runtime permission
  31  * "accessClassInPackage.*").
