Class ProtectionDomain
This class represents a group of classes, along with their granted
permissions. The classes are identified by a
CodeSource. Thus, any
class loaded from the specified
CodeSource is treated as part of
this domain. The set of permissions is represented by an instance of
PermissionCollection.
Every class in the system will belong to one and only one
ProtectionDomain.
