AbstractILFactory bug?

["Michał Kłeczek (XPro Sp. z o. o.)" <mi...@xpro.biz>]

I have just found this piece of code in AbstractILFactory:

Class[] interfaces = getProxyInterfaces(impl);
...
for (int i = 0; i < interfaces.length; i++) {
     Util.checkPackageAccess(interfaces[i].getClass());
}

So we check "java.lang" package access.

A bug?

Thanks,
Michal
