Examples of java.security.Policy$UnsupportedEmptyCollection

java.security.Policy
This class represents a read-only empty PermissionCollection object that is returned from the getPermissions(CodeSource) and getPermissions(ProtectionDomain) methods in the Policy class when those operations are not supported by the Policy implementation.


        // Setup the PermissionCollection for this web app context
        // based on the permissions configured for the root of the
        // web app context directory, then add a file read permission
        // for that directory.

        if( policy != null ) {
            try {          
                // Get the permissions for the web app context
                String docBase = context.getRealPath("/");
                if( docBase == null ) {
                    docBase = options.getScratchDir().toString();
