RuntimePermission

Synopsis

This class is a java.security.Permission that represents access to various important system facilities. A RuntimePermission has a name, or target, that represents the facility for which permission is being sought or granted. The name “exitVM” represents permission to call System.exit( ), and the name “accessClassInPackage.java.lang” represents permission to read classes from the java.lang package. The name of a RuntimePermission may use a “.*” suffix as a wildcard. For example, the name “accessClassInPackage.java.*” represents permission to read classes from any package whose name begins with “java.”. RuntimePermission does not use action list strings as some Permission classes do; the name of the permission alone is enough.

The following are supported RuntimePermssion names:

accessClassInPackage.package

getProtectionDomain

setFactory

accessDeclaredMembers

loadLibrary.li brary_name

setIO

createClassLoader

modifyThread

setSecurityManager

createSecurityManager

modifyThreadGroup

System administrators configuring security policies should be familiar with these permission names, the operations they govern access to, and with the risks inherent in granting any of them. Although system programmers may need to work with this class, application programmers should never need to use RuntimePermssion ...
