    Description

      URLPermission p1 = new URLPermission("wss://www.foo.com/-", ":X-Foo");
      URLPermission p2 = new URLPermission("wss://www.foo.com/", "");
      System.out.println(p1.implies(p2));

      results in:

      $ java Test
      Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
      at java.util.ArrayList.rangeCheck(ArrayList.java:658)
      at java.util.ArrayList.get(ArrayList.java:431)
      at java.util.Collections$UnmodifiableList.get(Collections.java:1309)
      at java.net.URLPermission.implies(URLPermission.java:267)
      at Test.main(Test.java:9)

      It's not expecting an empty list of methods in the policy permission (p1 in the example).

      An empty list in the policy to be consistent with the spec should only imply a permission with an empty list.
