LazyWeb: Advice on Started Threads
Code shows the problem best, so... Given the following sample code:
public void testSubjectFollowsSpawnedThreads()
{
// Never allow access to teacher
rp.addRules(Teacher.class, new Rules()
{
public boolean allow(Object subject, Object object)
{
return false;
}
});
Teacher teacher = new Teacher("Mr. Brown");
final ClassRoom english = new ClassRoom(teacher);
filter.setSubject(new Object());
// Verify subject set on current thread
assertNull(english.getTeacher());
final boolean [] blocked = {false};
final boolean [] finished = {false};
Thread thread = new Thread(new Runnable()
{
public void run()
{
blocked[0] = (english.getTeacher() == null);
finished[0] = true;
}
});
thread.start();
while (!finished[0])
{
Thread.yield();
}
assertTrue(blocked[0]);
}
I am trying to define a pointcut in AspectJ to match the beginning of the execution of the Runnable associated with thread. I need to be able to access some static context in the spawning thread and pass it into the advice (the current security subject). I have tried a couple things and failed to get it right =( I am seriously thinking that a static thread-local subject may not be the best way of specifying the subject, but I don't have a better one. Any thoughts on pointcut definition?
