Class RemoteClassLoadingPermission

java.lang.Object

java.security.Permission

java.security.BasicPermission

net.jini.loader.RemoteClassLoadingPermission

All Implemented Interfaces:

Serializable, Guard

public class RemoteClassLoadingPermission
extends BasicPermission

RMIClassLoaderSpi instances that implement net.jini.loader.ClassLoading.SafeUnmarshalling check before loading class files from a downloaded codebase, that the codebase's ProtectionDomain is permitted to load classes.

This functionality is limited to JERI and not supported by JRMP.

Note that a lack of this permission doesn't prevent loading interfaces. For that reason, static field initializers may be run, however interfaces are not permitted to use static initializer blocks, so cannot throw an exception such as ThreadDeath directly, or call privileged methods as a ProtectionDomain representing the untrusted interface is present in the current execution context AccessControlContext.

It is recommended for this permission to be granted to code Signers, or be granted after proxy preparation.

If this permission is to be granted after proxy preparation, a jar file can declare the permissions it needs granted during proxy preparation, see AdvisoryDynamicPermissions.

Users who want to disable this security check should use a wildcard "*" grant statement in their security policy file:

grant{
permission net.jini.loader.RemoteClassLoadingPermission "*"; };

Uses BasicPermission hierarchical naming conventions and wild card rules.
