The constructors of URLPermission class do not behave as described in javadoc

Following two constructors did not throw "IllegalArgumentExceptions" when given invalid url.
public URLPermission(String url, String actions)
public URLPermission(String url)
The behavior is not consistent with Javadoc descriptios:
    IllegalArgumentException - if url does not result in a valid URI
-------------------------------------------------------------------------------------------------------------
Ran test below with latest promoted binaries and test failed:

import java.net.*;
public class TestConstructor {
    public static void main(String args[]){
        String invalidURI="http:\\www.oracle.com";
        try{
            URI u = URI.create(invalidURI);
        }catch(IllegalArgumentException e){
            System.out.println(invalidURI+" is an invalid URI");
        }
        try{
            URLPermission permission = new URLPermission(invalidURI);
            System.out.println("test fail");
        }catch (IllegalArgumentException e){
            System.out.println("test pass");
        }
    }
}
