/** Test for Bug 732413
    Passing DISALLOW_INHERIT_PRINCIPAL flag should be effective even if
    aPrincipal is the system principal.

const nsIScriptSecurityManager = SpecialPowers.Ci.nsIScriptSecurityManager;
var secMan = SpecialPowers.Cc[";1"]
var sysPrincipal = secMan.getSystemPrincipal();
isnot(sysPrincipal, undefined, "Should have a principal");
isnot(sysPrincipal, null, "Should have a non-null principal");
is(sysPrincipal.isSystemPrincipal, true,
   "Should have system principal here");

var inheritingURI ="javascript:1+1");

// First try a normal call to checkLoadURIWithPrincipal
try {
  secMan.checkLoadURIWithPrincipal(sysPrincipal, inheritingURI,
  ok(true, "checkLoadURI allowed the load");
} catch (e) {
  ok(false, "checkLoadURI failed unexpectedly: " + e);

// Now call checkLoadURIWithPrincipal with DISALLOW_INHERIT_PRINCIPAL
try {
  secMan.checkLoadURIWithPrincipal(sysPrincipal, inheritingURI,
  ok(false, "checkLoadURI allowed the load unexpectedly");
} catch (e) {
  ok(true, "checkLoadURI prevented load of principal-inheriting URI");
