Sounds to me like you're accidentally declaring b.myC as a static, perhaps.
Actually, double check your examples (perhaps using the link report option
on MXMLC). It might be that you're not actually referencing B and it's not
becoming part of your SWF, in which case you're getting a "best guess"
object where you think you're getting an instance of B (you can't check for
"is B" without including it in your swf, but you can check for "!(is A)"
without including the B class.
In which case, it's the unmarshaller that's killing your data when trying to
convert it to a B (becuase now it knows to do it, once you've referenced the
class and it's in your SWF). Double check how you're defining C in your Flex
*and in your Java*.
Also, if it's the unmarshaller that's the problem, I'd definitely try a
compile against Flex 3.01 and see if the problem goes away. If you've got a
smallest-failiing case project for this bug it should only take you a few
minutes.
