Yes, we wrapper standard Java subjects with the JSSubject.java class.
General pattern is to execute a privileged action on the JSSubject
class:
Exception executeException =
(Exception)JSSubject.doAsPrivileged(userSubject, new
PrivilegedAction()

Lots of places. see DatabasePageManagerServer.java, or the PageManager
tests TestCastorXmlPageManager.java, TestDatabasePageManager.java ....
There are also examples of constructing a Subject ...
private Subject constructUserSubject()
{
// setup test subject
Set principals = new PrincipalsSet();
principals.add(new TestUser("user"));
principals.add(new TestGroup("group"));
principals.add(new TestRole("role"));
return new Subject(true, principals, new HashSet(), new HashSet());
}

All integration tests and standalone apps use Spring to bootstrap
Jetspeed. See the initialize method in JetspeedPageManagerServer.java.
It sets up the JNDI data source, and then points the
SpringComponentManager at the Spring configs necessary to run a page
manager.
