> all verifiers incorrectly assume that if a class is loaded then all its subclasses can be obtained by cl_get_class with classloader of the given class
> to prove that it's not always the case, apply "reproduce.patch" and run Eclipse 3.3. (I'm thinking of a smaller reproducer)
> To fix the bug (and not kill performance) changes in class_interface are necessary. See fix.patch (revert reproduce.patch before applying fix)
