Details:
At the end of _addFrameworkFromClass: in NSBundle.m, there's this section for
the case when the framework is linked to a bundle:
if (_loadingBundle != nil && _loadingBundle != bundle)
{
[_loadingBundle->_bundleClasses
removeObjectsInArray: bundle->_bundleClasses];
}
The problem is, I believe removeObjectsInArray: causes isEqual: to be sent to
the classes, which then will cause +initialize to be sent to the classes. I'm
pretty sure they shouldn't be initialized here, and in my case in a class's
custom +initialize method there is a call to [NSBundle bundleForClass: ] which
returned incorrect results because the removeObjectsInArray: method wasn't
finished executing.
I attached a patch which accomplishes the same thing and compares the classes
with ==, and this fixes my code (I was working on a UnitKit bundle to test
Etoile's SmalltalkKit.). Hope this is a correct analysis / helps :)
