Examples of java.security.Policy.refresh()

java.security.Policy.refresh()
Refreshes/reloads the policy configuration. The behavior of this method depends on the implementation. For example, calling refresh on a file-based policy will cause the file to be re-read.
The default implementation of this method does nothing. This method should be overridden if a refresh operation is supported by the policy implementation.

        try {
            // The policy file may have been modified to adjust 
            // permissions, so we're reloading it when loading or 
            // reloading a Context
            Policy policy = Policy.getPolicy();
            policy.refresh();
        } catch (AccessControlException e) {
            // Some policy files may restrict this, even for the core,
            // so this exception is ignored
        }
