Technically, "sealed" means "not dynamic". Almost all Flex classes are sealed. Your pain is that source isn't available for everything. That's always going to be true somewhere since not everything will be opensource.
Anyway, see if the debugger will show you the parameters to drawPolyLine. It looks like it ran points to draw before it thought it should.
