| <div class="block">Provides security-checked access to internal thread pools as a | |
| java.security.PrivilegedAction, to be used conveniently with an | |
| AccessController.doPrivileged or Security.doPrivileged. | |
| There are two internal thread pools: one of threads in the system | |
| thread group, for executing tasks to be guarded by the security | |
| policy for the system thread group, and one of threads in a | |
| non-system thread group, for executing tasks with user code that | |
| should not be restricted by that policy. | |
| If there is a security manager, the run method will check the | |
| ThreadPoolPermission for the requested thread pool. If used with a | |
| doPrivileged (the typical case), then only the protection domain of | |
| the immediate caller of the doPrivileged needs the permission. | |
| The thread pools execute an action in a thread without the security | |
| context in which the execute method was invoked, without any | |
| subject, and with the system class loader as the context class | |
| loader. Actions are expected to complete with the same context | |
| class loader and other thread-specific state (such as priority) | |
| that they were started with.</div> | |
