Alex Harui commented on FLEX-33987:
-----------------------------------

Can you post one or more of those stack traces?  Feel free to obfuscate class names of your
classes.

I'm just trying to determine how many people are going to be affected and whether there is
some other root problem. That code has been there for quite some time and I don't recall anyone
getting null in there, but I might have missed some prior bug being filed.
