Problem description:
====================
Specification for javax.smartcardio.CardPermission.CardPermission(String termName, String actions) states as follows:

---Quote from spec---
Parameters:
terminalName - the name of the card terminal, or *
actions - the action string (or null if the set of permitted actions is empty)
Throws:
NullPointerException - if terminalName is null
IllegalArgumentException - if actions is an invalid actions specification
---Quote from spec---

So, spec is explicitly allows to pass null actions parameter to a constructor.
But actually it throws an IllegalArgumentException in this case.


Minimized test:
===============
---Test.java---

import javax.smartcardio.*;

public class Test {

    public static void main(String[] args) {
CardPermission permission = new CardPermission("a", null);
System.out.println("Cannot be reproduced - exception is not thrown");
    }

}

---Test.java---
