Hello,
lately we changed the object format of subject class from variableByte
to normal one.
All projects which using NBExternalStructure can meet certain problems with it,
and first which comes is that it may load code cleanly but in fact
result in bogus
variable subclasses of NBExternalStructure , while it can't because
superclass has instance variable.
(i suspecting classbuilder bug, but need to verify first).
