title: access denied ("java.io.FilePermission" "<filename>" "read")
body: <p>I am making a game in Java using the framework pulpcore, I keep getting this error:</p>
  
  <pre><code>java.security.AccessControlExecption: access denied ("java.io.FilePermission" "scores.dat" "read")
  </code></pre>
  
  <p>Anyone have any idea how to fix this?
  I know that it is something to do with polices but I have never used them before so have no idea how to fix this. Any help would be greatly appreciated.</p>
