Bug 15277 Recreate test suite allows you to add the suite to itself
If you have a test suite that is also a test case (done to allow cascading tests), and recreate the test suite, you're allowed to add the suite to itself. This results in a recursive call to .suite(), which ends up causing a stack overflow when run. I'm not too sure on this, but I believe previously in this situtation the suite was added to itself a test case (new Suite(class) as opposed to class.suite()), which prevented this from happening. I do prefer this new behaviour, as it makes chaining suites together much easier (now if it only searched sub-packages for suites). This one special case just needs to be handled better.
