Java Tutorial Security trail - updating java.security file doesn't work

Question

I'm going through the Java Tutorial Security trail but I'm stuck at the "See the Policy File Effects" lesson (See the Policy File Effects lesson link. I can make approach 1 work. This makes me think that I haven't typo'd my policy and signed jar file. Approach 2, editing the java.security file, isn't working.

I'm working on Windows 7 using Java 7 (installed at C:\Program Files\Java\jdk1.7.0_67). I do not have a .java.policy file (although I did try this).

Here's the exception

$ java -Djava.security.manager -cp sCount.jar Count C:/tstsecdata/data
Exception in thread "main" java.security.AccessControlException: access denied ("java.io.FilePermission" "C:\tstsecdata\data" "read")
    at java.security.AccessControlContext.checkPermission(Unknown Source)
    at java.security.AccessController.checkPermission(Unknown Source)
    at java.lang.SecurityManager.checkPermission(Unknown Source)
    at java.lang.SecurityManager.checkRead(Unknown Source)
    at java.io.FileInputStream.<init>(Unknown Source)
    at java.io.FileInputStream.<init>(Unknown Source)
    at Count.main(Count.java:48)

What I've tried.

I noticed that I had several JDKs installed. I uninstalled all and then re-installed jdk1.7.0_67.
I noticed that 2 jre's are installed. One is Java\jdk1.7.0_61\jre. The other is Java\jre7. I found an explanation for this at Oracle JDK installs two JREs?. So I edited both java.security files and added the following line to each (after the policy.url.2 entry).

policy.url.3=file:/c:/tstsec/exampleraypolicy

FWIW, here's the policy file:

/* AUTOMATICALLY GENERATED ON Tue Jun 02 09:39:05 EDT 2015*/
/* DO NOT EDIT */

keystore "file:/C:/tstsec/exampleraystore", "jks";

grant signedBy "susan" {
  permission java.io.FilePermission "C:\\tstsecdata\\*", "read";
};

I tried making a copy of my edited java.security file and putting it in my /Users/ folder as ".java.policy".

My workstation is administered by the IT dept although I do have admin privileges. Is there some Windows 7 policy that is messing with me?
