Yes, you are absolutely right, all exported classes should be marking
the object variables.  For the ones you highlighted above, this could
only become an issue if somebody created a subclass of these classes.
Since they are not widely used, this apparently has never happened.
StackFrame and Exception have never been in a released version, but
the Exception class is definitely intended to be something one would
subclass.
