Stumped - class cast is not working [message #86735]

I have a piece of code that looks something like:

Object object = someFunctionCall();
Type[] types = object.getClass().getGenericInterfaces();

inspection of the types[] array shows two interfaces:

test.Foo
test.Bar

the following code causes a ClassCastException

test.Foo foo = (test.Foo) object;

Some things to note:

someFunctionCall() is in a different bundle
test.Foo is in a defferent bundle

Does anybody know how this situation can happen? I'm totally stumped.

It turns out that if I Import-Package on test.Foo instead of
Require-Bundle that contains test.Foo, it works. Is this a bug?
