Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

This
deprecated class represents a
Subject-based security policy. Because the JAAS API (this package and
its subpackages) were introduced as an extension to the core Java
platform, this class was required to augment the
java.security.Policy class which, prior to Java
1.4, had no provisions for Subject-based authorization. In Java 1.4,
however, java.security.Policy has been extended to
represent security policies based on code origin, code signers, and
subjects. Thus, this class is no longer required and has been
deprecated.
